Obviously I can't see what hardware models you are using or your image refers to, however you can go to:
Dashboard > Organization > Monitor > Firmware Upgrades to see what releases are available.

The one listed Upgrade available is due to MX18.211.5.1 being the most current stable release version (or whatever the most recent release would be based on your hardware model).
