Cannot claim account, Game: Brawlhalla

Hey there,
I am currently trying to claim my account on for the game Brawlhalla.
Next to the name, it says that, the profile is currently unclaimed. When I press the “Claim Profile” button, it just redirects me to the linked gaming platforms. As I play Brawlhalla via Steam, I linked my Steam account, but nothing changed. Is there anything else I need to do in order to claim my profile?

Out of unknown reason, my twitch channel-link is displayed on the Brawlhalla profile page, even if it is not claimed completely.

I’m having exactly the same issue. Pretty irritating.
