Hello guys, another bug here:

I have a setting page containing a filed group that contains a field and another add_more field group.

When saving the setting page after adding an add_more, the fields get duplicated. Meaning if I’m trying to save 3 fields, I’ll end up with 6…

Note also that after saving, if you have any color picker field like I do, the color picker widget will not be available anymore.

FYI: Same behavior if these fields are added to a post meta-box instead of a setting page.

This does not seem to happen if the nested field groups does not contain an add_more field

Here is my code, you can use it in a setting page or meta-box, thanks:
