Help with grinder

This is the grinder I use for brewed. A few weeks ago a piece of metal got in somehow, fml, I took the front apart and cleaned it. I put it back correctly I think, but now the grind size is wrong, I have to go all the way fine to get a decent drip grind. I have read the manual, and taken it apart twice, I don't know what to do.
Tia!
