Power Apps not showing all the data from the dataset

[Slick269]

I am getting an intermittent error as in some users have the issue and others don't. I myself have the issue whereby on a matrix table and only on some columns (which happen to be sourcing data from a separately linked table) , the Power Apps is showing 0, but in the Report in the Workspace, we have values. Even when I update the App and show preview, it shows the values, but immediately I go to the App, it goes back to 0. For awhile it was only doing it on Edge but now it seems to be doing it on Chrome & Opera as well.

I can't work this out as it seems to only be happening at the Power BI App front end and not the backend. Anyone know how this issue could happen or how to fix?

Found the error was linked to a date slicer that was not working properly due to incorrect format (Date/Time) linked to a Date only field!!!
