Lightroom CC Android is removing Titles & Captions

I have synchronised a collection in Lightroom Classic CC. The synchronised photos are displayed correctly in Lightroom Classic CC "All Synced Photographs" and in my Lightroom Library on the web. I then synchronise Lightroom CC on my Android phone and view the photos using the Info view. On the first pass, the photos are displayed with Title and Caption as set in my Classic Catalog. I then display the photos on my phone a second time and some of the Titles and Captions disappear and are replaced by "No Title" and "No Caption". The titles and captions of these images are also deleted from the web Library and from my LR Classic CC Catalog. This happens on some images and not others.
