Kerbal Space Program

I have been experiencing a bug that is really messing up my missions on Xbox. When ever I place any Kerbals in any type of space stations the multiply to a random number. could be just two three or four or more its random. when a kerbal is cloned and I try to return any of the cloned kerbals or the original kerbal back to KSC it will say in the de-briefing that they have returned but as soon as I go to the VAB or the SPH they are gone. in The Astronaut Complex it says they are still on the station. The only solution is to remove the kerbal from the space station and get them far away and then EVA all clones and Terminate them in the tracking station. This only happens in space station not bases planet side or any other type of vessel. Please please fix this because in this current state space stations are unusable.
