Where do PLG_FAVGDPR_*-fields on registration page come from?

-- url of the page with the problem -- : joomla4.vierimpott.de/register/user/form
-- HikaShop version -- : 4.6.1
-- Joomla version -- : 4.1.5
-- PHP version -- : 8.0
-- Browser(s) name and version -- : Chrome Version 103.0.5060.114

Guys and girls, I appreciate your help.

If you look at the provided URL there are three fields starting with PLG_FAVGDPR_*

I checked all options but I simply have no clue where these fields come from.

Any hint would be very appreciated.
