Thank you very much Brajesh! That fixed the issue with overlap. I’ve still got some field description values showing twice though. Do you have a quick solution for this as well? 😉 I’ve contacted my theme support with this issue, so no pressure!

Otherwise, when I use multiple member type fields in registration form there’s no problem with assigning the types or modify them later. The only problem I notice is with BuddyPress not showing/sorting the members correctly in the “members” directory. For me, the most important function was to assign multiple types, rather than being able to sort the members associated with them, as I use this feature to automatically restrict users to certain subsites according to what type they chose during sign-up. Maybe not the most straight-forward way of doing things, but still, it works. (One subsite for every member type. I’ve created a role without any capabilities/permissions, and every subsite must assign all the other member type with that role for this to work)
Best regards, Johan

Sorry, I’ve got it. Wasn’t logged in as super admin on subsite. That did the trick! Thank’s anyway for your swift reply! BG, Johan
