Can't get my full stack cert (bug)

According to this post I automatically get a Full Stack Cert when finish all 6 projects.
But my project counter has a bug and I believe I did not get my Full Stack certificate because of this bug.
See the image below.

Quincy replied to my post about this yesterday, I finished also. The issue is that the full stack cert claim button hasn’t been coded in. But it definitely will be available.

There’s an issue on Github for it.
I had a look and although I could probably think how to code it in, as a first contribution I’d be fairly nervous about the whole thing.
