Dex-Chan icon and Mangadex need your suppor banner still shows for subscribers

[Leuenberg]

Hello kind maintainers.
Not sure if it is a bug or just normal behavior, but as said in the title, I subscribed to namicomi to support Mangadex using same email But the Dex-chan, banner on top of page and pop-up on page footer are still nagging me (not that I complain for Dex-chan).
Regards,
