Bridge 2023 Stack problems

Bridge 2023 13.0.1.583

MacOS 12.6.1

PS 24.1.0

1. I have many files in different folders where I stack individual images and their "components" )tiff, NEF,jpg_ in one group per image

When Bridge now closes in one or more folders many groups are magically UNGROUPED by themselves 

All by themselves. 

2. If I remove an image from a group the count no longer decrements I have to instead UNGROUP the entire group and restack / group to get the count to be correct
