I'm not sure what's going on. Even though the main component is active, as soon as you create an extrude a different component becomes active. Looking at your design timeline I have to tell you it's a complete mess and I'm not suppressed Fusion's getting confused. Some pointers, fix all warnings and errors in the timeline. If you have a move in the timeline you're probably doing something wrong, if you have a capture position in the timeline you're probably doing something wrong, same goes for remove. I don't know if you'll be able to fix the problems now because you have so many. Look at Rule #1 and start again would be my advice and ask questions before getting too far.
