Screen control changes after UI upgrade

Hello Experts,

we upgraded our UI and now persona flavors in mobile devices showing a label which I do not see in laptop browser.

Is there any parameter or configuration available through which I could hide it as its creating problem for user, we are not using the lower label showing persona P icon or the enter button shown here in picture.

In chrome or edge browser I do not see the three dots or F11 or Enter any where. But in device its visible on all most all screens.

Appreciate your help.

Regards

Ritesh
