Manual backup oddity

i wonder if others have noticed this:

following a restart of the roon client, for example after applying an update, the first time i attempt a manual backup, and after selecting the location of the backup, the ‘start’ button is grayed out and insensitive. i have to quit the roon client and restart, at which point the ‘start’ button is now operable.

nothing more than a minor annoyance, but since the behavior has survived multiple updates, i assume that it is either overlooked or regarded as too trivial to fix.

Have you tried specifically single-clicking (‘again’) on the destination square ‘button’ top left of the relevant dialogue - carefully avoiding the ‘X’; it sometimes seems to need to be re-selected?
