Hello, @t.james
Thanks for these details.
As it was mentioned in my previous message, that nested RG and plugins inside them could perform incorrectly.
The best solution for your case is to avoid using the nested Repeating Groups (with this plugin) or to remove one of the conditions, mentioned above. We suppose that the searching conditions of the parents RG indeed can influence.
Allow me to note that we deal only with the general support of our products and fixing the bugs, however, in your case, the issue was reproduced by the elements overlapping.
Please try to change the conditions, mentioned above, and give it a try one more time.
Best regards,
