Fenix 7 remove useless maps

Hi 

I'm a french user of Garmin Fenix 7

This forum has been very helpful previously to know the difference between "adventure" and "trekking" activities

I'd like to remove useless maps pre installed on my Garmin Fenix 7

The user guide says "when connected to a wifi network, select the map, press the start button and select remove"
I did connect to a wifi network, followed the instructions but the start button shows only the version of the map, without any possible removal action

 Thanks for help
