@mrtoyota03 - thanks! I added your contact info on a development team team looking into this. We noticed it happens only on some TIFF files, not all TIFF files - and will tag you once a fix found. Make sure to test editing with the original files which would be JPEG or RAW format and will not get these thumbnail issues. You can also revert to [v4.0.1](https://community.topazlabs.com/t/topaz-photo-ai-v4-0-1/91794) until it’s fixed!
