I'm receiving this warning for every single coil placed in the air loops:

** Warning ** In calculating the design coil UA for Coil:Cooling:Water VAV_MID WITH REHEAT CLG COIL
   **   ~~~   ** the coil bypass factor is unrealistically large;
   **   ~~~   ** The initial design conditions are: Tair,in = 24.1475
   **   ~~~   **                                    Wair,in = 9.020714E-003
   **   ~~~   **                                    Twater,in = 6.6667

Cooling coils are auto-sized (in 2A climate zone). As suggested here I tried to change the inputs in sizing:system and sizing:plant but the warnings are still there. Here are my inputs for above-metioned objects.
