sd card not visible in card manager

Good morning
I have a montana 700 with a Garmin Topo France V6 micro SD inside, my topo mark was visible in the map manager list since I updated to firmware 22.70 and the update Topo Active Europe West and Central and East maps I no longer see my Topo France V6 map in the map manager list, I called Garmin, a technician gave me a procedure to do a reset settings and another technician tells me that it is normal that my micro SD is not displayed in the list. When do you think? THANKS
