I was using the wrong version of the game with the mod.

Recently, I have been experiencing an issue within the Space Plane Hangar concerning staging. Whenever I add a jet or turbofan engine to my craft, the stage for the engine does not appear. This occurs in the VAB and SPH, but is usually not a problem in the VAB as I do not use aircraft engines much there. This problem started after I installed the B9 Aerospace mod, which I think I have properly installed but I may not have. Here is my list of mods: X Science AJE (?) B9 Aerospace (B9 Animation Modules, B9 Part Switch, Firespitter, JSI, SmokeScreen) ChopShop Destruction Effects Kerbal Engineer (It's outdated, but still works fine) Kerbal Konstucts Kerballoons KWRocketry Procedural Fairings RealPlume (?) SETIrebalenceReactionWheels (?) SmartStage Smokescreen (?) Solver Engines (?) Squad (Stock Parts) I have added a question mark to the mods whose functions I've forgotten. Hopefully you can help with my problem. Thanks!
