I was done with a project so I deleted the tag related to the project in Allusion, this action however removed all other tags attached to said images as well, but didn't release the image into the "untagged images" sorting menu. The icon does indicate 5 images untagged, but the menu itself shows nothing.

I have attached screenshots to show both the untagged images menu, and an example of an image that I found under "all images" later with all tags purged.

Allusion version v1.0.0 rc7.3

Windows 11 Home
