Signed Document not being returned to source folder/document set - for some users. Any know fix?

We have been setting up a new SharePoint library for contracts and using the SP integration. 

When I and a couple of other users test it, it returns the doc the source folder/document set.  We are using Document Sets but works the same for folders.

Our main user however gets signed docs returned to the root folder. 

DS site says it’s a know issue. Docusign documentation

Anyone found a fix yet?
