Custom preset not showing up.

[Menisco]

Hello, I'm trying to implement a custom preset, because one of our hospitals uploads funky images and it's annoying to change the window/level for every single DICOM.

I tried adding the following line to the presets archive but it didn't show up as an option after opening the DICOM:
<preset name="HRSP" modality="MG" window="165" level="165"/>

Changing the modality to CT or RM made it show up and function as intended on DICOM's of those modalities.
I thought it might be the DICOM archive modality, but it seems it is correctly assigned as MG.

So, am I doing something wrong or is the problem really in the files?
Is there a way to implement a preset available for all modalities?

Thanks in advance!

I don't see any issue to add a MG preset:
