Tinkered with settings and now the contents of some containers won't show or wrongly display

Describe the issue

Good evening,

when I logged into my game today I noticed that WTHIT started to show the Energy Bar for FE on every block with an Inventory. It didn't do that yesterday (and I didn't change anything from yesterday to today). I opened the config and tinkered with the settings like fluid display, modern or classic, lists, grids or dynamic and such stuff. Found the option to turn off Energy display but I had to manually change it in the configfile as the setting sort of didn't stay on false. Restarted the game then after manually changing the configfile file for that option and even found an option to display the item count.
But now WTHIT will show me the "Iron Knife" of Farmer's Delight as only content in containers like the Storage Drawers of the Storage Drawer Mod and of the Backpacks of Sophisticated Backpacks even though those Containers don't even contain an iron knife. Before I tinkered with the settings to turn off the FE-energy bars (as I don't use any mods that would need them) and played with the display modes of container contents, WTHIT would show me what was inside those containers mentioned even though without numbers.

Is WTHIT actually not compatible with Sophisticated Backpacks and Storage Drawers and it working with those containers before was just some sort of fluke, or are SD and SB probably not compatible with showing numbers? I'm confused...

Im on the latest version for NeoForge 1.21.1

Cheers!

EDIT: After forcing the crash for the log it works again but now WTHIT shows me the content of one of the backpacks on the stoves of Farmer's Delight o__O something isn't quite right ever since I tried out different viewing options and enabled to show the block count...
EDIT 2: Just noticed that the content of that backpack in the screenshot is now displayed on all containers of Sophisticated Backpacks. I quit the game and restarted it and now everything is back to normal except for Sophisticated Backpacks contents not showing at all and Storage Drawer Blocks nor show the full entity name instead of just the Name ob the Block (like before it was "Oak Drawer 1x2" and now it is "block.storagedrawers.oak_full_drawers_2") I wonder what WTHIT will display when I restart the game again... :'D

The actual content of that backpack

Hello, I will update this with some fresh info.
Ever since I posted this I watched very strange behavior. Everything works as intended with vanilla inventories, but when it comes to mods the "funniest" things happen.
Whenever I use the cutting board of Farmer's Delight all the mod inventories like placed Sophisticated Backpacks or Storage Drawers will display to only contain "Iron Knife" like shown in the screenshot above. I however used an iron pickaxe yesterday and mined a cutting board with an iron knife on it. Afterwards all modded inventories showed to contain "Iron Knife" and "Iron Pickaxe" (when actually being either empty or containing different things).
Something else I noticed is, that the content of backpacks is sometimes shown correctly on one Backpack but then this "image" of contents is shown on all other backpacks and other modded inventories.
If one of the above mentioned bugs isn't happening WTHIT shows no contents of filled modded inventories (Sophisticated Backpacks and Storage Drawers in this case) altogether.

It is like this, since I tinkered with the settings to disable the FE-Energybar that started to show on everything with an inventory - even vanilla chests and barrels. While I was at it I noticed a lot of other configurable stuff and switched it false or true to see what it would do. I did however only tinker with settings that are meant to be configured like switching on and off showing liquids or showing infested blocks or such stuff.
