The issue here is that the user is using the new field groups option in our Toolset Beta plugins and wanted to display the repeated groups on the frontend.
I spoke with the development team and they said that they are working on an API for the repeatable field groups but its not quite ready as yet.
So for now we are not able to display this on the frontend.
The solution I provided was for the old method of repeatable field groups but given that you are using the Beta we currently don't have a solution for it just as yet.
