Deleting one anchor point inside of a group deletes all anchor points

Adobe animate 19.1 build 349.

64 bit windows 10

if a create a shape (line, circle, rectangle, misc) with multiple anchorpoints and then group that shape about 50% of the time when I go inside the group and try to edit the shape by deleting individual anchorpoints, the entire shape will delete.

sometimes breaking the shape then regrouping fixes this.

This is a big inconvenience since I like working with groups to organize artwork.

I would like to be able to delete singe anchorpoints at a time. I like how the deleting single anchorpoints does not break the line, but just removes that point.
