I just fixed this problem from another user post where there was more than 1 AirloopHVAC:DedicatedOutdoorAir object in the simulation. Only the first sized correctly. See GitHub issue. The only thing I can think of to get you running again is to hard size the coils for the first DOAS and then run again. Then hard size the next DOAS coils and run again, etc. Sorry for the head ache.

Update: you said you added a DOAS so there is only 1 DOAS. To size properly the simulation also needs SizingPeriod:DesignDay to find the outdoor conditions used for DOAS sizing. Maybe all you need to do is add summer and winter SizingPeriod:DesignDay objects.
