GitHub Pull from Forked repository

So I am working on a repository that is forked from my team.
I did my part inside a branch, pushed and is merged.

On my end, I still have the branch with the changes.
I merged to the master within my own repo.

But now, my master is out of sync from the base’s master.
Every time I tried to pull, it says that I am already up to date even though I can check from the that both repository is out of sync.

Did I do something wrong?
