I also have just realized that the "Mark All" "Unmark All" button in the Export tab also don't work. I can manually select tracks from an album but this doesn't actually start anything.

Sooloos, Roon, G series (with LPS upgrade), 800 series (with LPS upgrade), HD621, AC200, Prime and PS, DSPs old and new.

Purdeys, Moke, Leica, 'Blad. Only the best.
