Hi @James Eggert
Are you using a form based on a list?
Per my research, this is a limit of list based forms. A list based form is flat, it is not possible to build hierarchical information sets with grouped and nested items, that's why the Repeating Section is missing.
You could use Qrules tool or recreate a new form to meet your requirement, here I find two similar issue and methods provided in the articles:
