NFT Marketplace from Nalfe - any ideas how this crap works?

I recently joined bubble.io. used NFT Marketplace from Nalfe as template I would like to customize further. Once my app from this template was created, I navigated to editor to customize it. Upon change of some settings it turned out I need to upgrade from free to professional plan, ok, I did it. Then I started customize this app further and I was very surprised to see that actually both dev and live versions have some weird un-disablable popup


I’m very upset, it basically somehow tries to connect to Nalfe and I don’t know why, but I can’t in live mode register as new user on my app (so basically it doesn’t work - these buttons are not present). Is this Nalfe a something which someone used?

I’d suggest contacting Nalfe if their template has problems. It isn’t something Bubble created.
