When I found the ghost block glitch, I found even more problems. The 2nd block that got combined got locked. That means I can't break it. Now instead, it breaks blocks below it, even though my mouse is at it.

You can’t break it because it’s not actually there. Relog or move the world border out one block to fix it.
