Kerbal Space Program

When the cover of SM-25 Service Module is jettisoned, the covers are almost bugged, dont go away, and have no hitbox thus going through my ship everytime I jettison them. and after switching to another vessel thats outside of the physics range the covers come back to the module, but I cant jettison them this time, which makes it extremely hard to reach to the parts taht I've put inside the service bays(stuff in the middle of it is still easly accessable but the stuff in the containers(?) that are located at two opposite sides of the service bay are extremely difficult to reach.
