Data grid Mobile - unexpecged Hilite

[hrcap]

Evening All

I hope that everyone is well.

I have a funny occurrence that I have spent the last two days trying to figure out but cannot for the lift of me work out what's causing it.

It occurs when using a data grid on mobile.

If I click on the datagrid the boarder of the datagrid seems to hilite itself which I don't want to happen. My older data grids do not do this but the data grids that I have added to my solution in the past week do. I have added two screenshots to show the undesired behaviour. (the bottom photo shows the data grid prior to it being clicked, the top photo shows the data grid after it has been clicked).

Is there a setting that I can change to stop this from happening?


Many Thanks
