Forge not updating branch

Hello, I've set up a server on AWS and it was working fine. As some point i've changed the branch and from then on i can't switch to another branch. On deploy i get:

From bitbucket.org:repo/branch_name
 * branch            development -> FETCH_HEAD
Already up to date.
Restarting FPM...

But when i do a git branch it shows the previous one

With git branch -a it shows only the old one and only this on the remote list.

Maybe i miss something but is it supposed to work that way?
