Maps on the device have an update even though I have updated them using Garmin Express

I updated the maps by plugging the Garmin 850 to my windows laptop and using Garmin Express, I updated the European maps to the latest version version. When I disconnect and reconnect the 850 to Garmin Express, there is no longer an option to update European maps.

However on the device itself, when I navigate to map manager it gives me the option of updating the European maps.

How can I check the version of the map on the device and why is Garmin Express and map manager on the device telling me different things
