[Resolved] Cannot delete repeat fields values

Hi,
I have created a Post Field Group with a repeatable group inside.

In my posts, the fields appears correctly and I can create items. My problem is when I try to delete the value: upon saving, the items are created once again - just empty.

See what I mean here: hidden link

I guess there is something to do with the fact that I have changed the name to the group and the fields. When I went back to the post, the fields were still there, empty, and it's impossible now to delete them

How can I get rid of them?

I think I have solved the problem - changing the slugs again.
