[Mod Portal][Bug] Reduntant notifications

[Linver]

Hi! I got a problem with the mod portal. Each time that I log in the mod portal I receive this notification:
"Invitation to collaborate on MOD X"
If I look in the notification page, click on the mod link, reload... nothing works, the notification still here, and when I log: "one new notification".
Thanks all for reading and for the attention.

Ps: I'm already a collaborater on that mod from many days.
