WIPilot1993

Just recently switched to trying the LevelUP 737. I have done two flights so far that went perfect until final approach. The aircraft trim seems to runaway (its not really a runaway but for some reason it just wants to really pitch up and put itself into a deep stall) to full up. Even when my speed is fine and I am lowering flaps accordingly to help with lift. I have many upon many hours between the Zibo 737 and the PMDG as well and I don't believe I am doing anything wrong here. Has anyone else had similar issues? Is this a known bug/issue? Thanks
