Ansys Fluent: subsonic flow accelerates in divergent duct

Hello, I'm simulating a supersonic external compression inlet in Fluent and for some reason after the normal shockwave the flow does not decelerate in the divergent while being completely subsonic. I've tried different geometries, outlet boundary conditions and subsonic initializations but nothing worked. Any help would be greatly appreciated.
