I have a form with a Repeating Section. A workflow runs on submission with an Update Item action that updates a field in the list. This deletes the contents of the repeating field.

This isn't entirely unexpected as the Repeating Section requires a Multiple lines of text Column with Append Changes to Existing Text. As we all know, when a list item contains a column like this, it gets updated each time the list item is updated. Even if nothing is entered into the column. Its been like this all the way back to SP 2007.

How do we overcome this?

We are running SP2013 on premise
