Hi @dhock ,
Could you please share more details about the Filter you used within your Gallery control?
Based on the issue that you mentioned, I have made a test on my side, and don't have the issue that you mentioned. Have you taken a try to save your SP List records into a Collection, and use the Collection as data source within your app?
On your side, please consider save your SP List records into a Collection, then use the Collection as data source in your app instead of the Original SP List data source.
Set the OnStart property of the App control to following:
ClearCollect(RecordsCollection, 'YourSPList')
then set the Items property of the Gallery to following:
RecordsCollection
If the issue still exists, please consider remove the SP list connection from your app, then re-create a new one from your app, then try above solution, check if the issue is solved.
Please also consider submit an assisted support ticket for further help through the following link:
