Creating new island with same name gives verse error.

Hi All. After playing around with various maps, I’ve archived a whole bunch of test ones as there isn’t a way to actually delete them. I’ve made sure they’ve been removed from the local system. So I try to setup a new project with the same name as a previous one and I get this message.

Can’t figure out how to get rid of it and only seems to happen on this one. Other ones I’ve created and archived are ok if I choose the same name.
There is obviously some link somewhere as I was using Verse in that island.
Cheers
