Answered Special badges progress

[Mortimer]

I'm not sure if it's me, but I've done all the special battles. From Team Rocket to Skull, but if I look at my badge progress, I see a grey circle at the end as if I didn't complete one. Is it because I didn't complete Galar or am I missing something? 😅

After team Skull comes Team Yell.
Team Yell has not yet been released, so that's greyed out for all of us.
