The sign of the computed mass flux value depends on the orientation of the integration plane’s normal. In your case it is likely pointing in the opposite direction of where it should.
For the region size: Can you post your whole example code / the geometry setup? (Just to make sure that there are no other issues, your setup of the plane integral functor looks correct).
