My level keep create temporary actors for my character

My character was acting normal as first, control able. But I did something wrong and it keeps floating whenever I start my level.

After awhile, I realized that there are temporary actors that made my character floats every time I play the level.

I tried to delete my character and add a new one but the new character will also float because of the character temporary actors.

So I decided to delete my character on the screen, then start the level without any character. Surprisingly, the character temporary actors appears on the screen and it’s control able like any normal character but I cannot change its stats. Like I said, it only appears when I start my level because right now my level has no character.
