Garmin Golf App: Disappearing Driving Range Sessions

Hi,
I have been playing with an Approach R10 for a few sessions at the range. Its great so far! 
But I have a weird problem with the app.

The first 3 sessions are visible in the Golf Sim Sessions part of the app, however any of my most recent are not. 
Actually they are visible, for a split second when i first open the sim sessions from the menu.

Then they disappear, and the first 3 sessions remain on show.

Any help appreciated

My Phone is an Android, Huawei mate 20 pro.

Thanks,

AL
