map data field "0" and no possible to change

dear, running last fw 11.00 on a fenix 5 plus. Maps version 2019.20. I want that during and activity with map view, see on it a datafields like pace and HR.

When I enter on the configuration of such specific activity (running), I go to the map screen, I push start (the pen) and the first option is the layouts to see (0 by default) when I push enter, instead of give the chance to modify this field, it returns again to the map view screen.

Is this normal?
