Update: 07/12/2017: Issue still exists in Nov 17 Patch 1. I have uploaded Sample data and .qvf to the original post.
Downgraded from NOV 17 to SEP Patch 1.
Synchronised and Reloaded the script (No changes). App data is now loading correctly.
Seems like a bug with the Data manager in the latest version.
The QVD Contains confidential data, but I can try to replicate with a sample data if anyone is still interested.
