LR Mobile on ipad - wrong number of photos on collections

iPad Pro running Lightroom Mobile.  Several collections show the wrong number of photos in the collection.  Seems to always be less than the actual total.  Numbers are right on iPhone, Desktop, and the Adobe Cloud.  I know they are wrong because it says a collection had 104 and everywhere else it says 111.  When I count the photos on the iPad there are 111 not 104.
