Go to the Map Tools View
Click on "Edit" beneath the Families
Enter Title for first Family
Enter Title for second Family
Result: (after a surprisingly long waiting period) the first family name is changed, the second remains unchanged.
This bug is not reproducible under ubuntu. Beside that, it doesn't seem to be really a bug and does not depend on how many familiy descriptions are changed. It seems that under macos the modify-event of the celleditor for the description is not triggered if you change a description without hitting 'enter' or unfocusing the the celleditor. Hence, finishing the dialog in that state, does not adopt the changes.
