Created attachment 180789 [details] Shows how the buttons are misaligned. SUMMARY The buttons (move up, delete) for the first language in the language selection list are not aligned with the buttons for the subsequent rows. See screenshot. Once one changes the order of the languages or adds/removes a language, all buttons are aligned just fine again. STEPS TO REPRODUCE Unknown! I did not find a way to reliably reproduce it. It happened *sometimes* after a new language was added and then one navigated back to the language selection screen. *Maybe* I resized the window in-between.
Aha, I found a reproduction. When I press [Defaults] in the main Region & Language screen (,for some reason, ) the selected languages reset to (American English, Español de España, Deutsch). When I reenter the language selection screen, the buttons of the first item are *always* first misaligned. Changing the order, adding or deleting any language makes the items align correctly again.
