Can't overwrite (Multiple values) in Bridge 2023 Mac OS with null value

When selecting files with differing metadata, deleting the field doesn't change the actual tag. For example if photo1.jpg has the keyword "Dog" and photo2.jpg has the keyword "Cat", I can't select both and replace it with a null value. The metadata remains unchanged, and therefore (Multiple values) is still displayed. Previous versions of Bridge did this correctly, but the new version does not. Clicking the check box to apply metadata changed doesn't work, nor does hitting enter or just tabbing to a new field.
