Nik Images Not Showing

Hi there.
Since the most recent updates (last week or so), when I finish editing an image in any Nik software and apply the changes (returning to the DXO screen) my Nik images no longer appear in the camera roll along the bottom. I have tried “refreshing” the folder from the photo library but they only appear after I either a) exit and reload DXO PL9; or b) open the folder from windows explorer, choose the Nik .tif and right click → open with → dxo.

What am I doing wrong,
Thank you so much for your time!
