Coaches A gym and B gym at a meet

[gymcoach20]

The meet I'm heading to this weekend not only has a flight A and flight B, but also has an A gym and B gym with different sets of equipment. Gym A includes a Modified Capitol Cup format while Gym B includes a Modified Traditional Cup. I've never experienced this before so I'm a bit confused. Does each flight perform in their own gym and a group warms up while a group competes or is there a warm up gym and a competition gym?
