Repeater items not deleting in Perch 3

Hi, I can confirm I'm having the same problem in Perch 3 as was happening here - https://forum.grabaperch.com/forum/02-17-2017-perch-repeater-not-getting-removed-from-blog-app

If I try to delete all the items in my repeater at once and save, none of them are deleted.

If I remove one item and save, it will delete, but when I get to the last one, it wont delete.
