I’m having kind of the same issue with the current version (5.1.7.1). When moving nested repeaters or adding an item between, items get duplicated. We set up several repeaters that change their fields depending on the type of media you select. It’s a List of filed like this:
When you select “PDF” you get the fields “Name” and “File”, when you select “Link” you get the fields “Name” and “Internal Page”, etc. You get the point.
What seems to happen when you move an item in the list is that ACF does not erase the subfields correctly and this duplicates entries. These duplicate entries do not appear in the backend but in the frontend.
I replaced ACF with version 5.0.9 and now it works fine.
Anybody having the same issue? Is this issue known already?
