The explanation lies with the zone sizing and the autosizing of the air terminals. The flow in an air loop is usually going to be the sum of the flows requested by the air terminals on that loop.

Otherwise you are mixing autosizing and hardsizing in the same air loop and this is the sort of thing that happens.
