Thumb preview not showing for models in sub-directory

[zhupeter010903]

First let me thank you for the great functionalities! I run into a small issue when exploring the manager.

The preview is working very well for models located directly under the target directories, model/loras, model/checkpoints, etc. But preview fail to show up for models in sub-directories, for example, model/loras/SDXL, models/loras/FLUX.

I need more detailed information to reproduce this issue.

The model preview in sub-dir works fine on my end, but I found that there are others who have the same problem as you.

Can you provide the following information to help me check this issue?

• OS version
• ComfyUI version
• ComfyUI-Model-Manager version
• Browser version
• Model and preview path in your local, like this:

models
    - checkpoints
        - sub-dir
            - a_sd_xl_base_1.0.safetensors
            - a_sd_xl_base_1.0.webp
            - a_sd_xl_base_1.0.md

• Response of /api/model-manager/models, like this:
