Fill pattern of molten polymer in Solidworks plastics

i am filling a mold which has 2 injection locations.  When i look at the filling pattern of the molten polymer, it looks a bit strange (please see the attached pic).  This is a snapshot at an intermediate time step.  You can see that there are patches which are surrounded by molten polymer.  I dont think this can happen in reality.  Has anyone seen this kind of behavior  or know why is it happening?


PS: the mold temp is uniform all throughout.  there aren't any local cold spots.  This is a solid mesh.
