Hello @casey.lanthier,
Thanks for reaching out!
First of all, I would like to suggest you check the example setup for this function on our demo editor page, here you can find the link: Zeroqode-demo-23 | Bubble Editor
Please pay attention to the Group S setup. Also, the “Move” custom event on the workflows tab and “A draggable RG dropped in another group” events for “DraggableRG C” and “DraggableRG B” elements.
Make sure you have all the required custom states that you will use in the “Move” event.
As for the repeating groups’ setup, specifically, the Data Source: after adding the Sort table you need to change the “sort by” parameter to “Sort”, and set “Descending” to “no”. Example from our demo: Screenshot by Lightshot - Screenshot by Lightshot
And for the plugin element setup, please make sure you have set the correct setting of the “Things” field. It should correspond to the “Sort” table: Screenshot by Lightshot - Screenshot by Lightshot
In case the issue still persists, please share the details of your setup (screenshots, video recordings). This will allow us to identify any possible cause much faster.
Best regards,
Gulce
