My next section is unlocked when I never completed it. All the problems have been done so I can’t learn them. I’m suppose to be on 15/18 lists and functions

Same thing happened to me. I stopped in the middle of List and Functions last night then when I signed back on tonight, I was in the middle of Battleship.

I ended up resetting my progress which put me back to very beginning. Kind of a pain but thought redoing would be good review. Unfortunately, now the instructions and the compiler are not synced up. The whole interface is fouled up for me.
