Group box is always white, hence unusable on AppleTv4k

Bug on AppleTv4k … the A,B,C,D group box is always white, can’t see the letters inside it to select. Happened in the latest upgrade of Zwift I think, at least I never noticed this behaviour before:

Hey Eiki, thanks for the heads up! As Lindsay said on Facebook: This is a bug with late joining events that have more than one subgroup and will be fixed in the next update.
