WPMU DEV advertisement active even though I am a member...

Why is the WPMU Dev still active on my multisite even though I am a paying member?

See the screenshot:

Why does this not run as white label?

I understand that this is shown while you are not a paying customer, because you guys want to sell, but there is nothing to sell to a already paying customer, right?

I do not wish to see my coming customers so see this ad, that doesn't look very professional as so to speak. How can it be removed?

Thanks!
