Are u sure its this is not referring to a different FW of another component?
Maybe you can upload a screenshot of your inventory page to show the FW versions. So far I would not recommend that you install FW 2.10.
Another possibility, maybe u can upload your garmindevice.xml to a filehoster and send the link by PN. I would like to have a look on this
Sent you a PM with the link of the garmindevice.xml

I hope you will finally solve the mystery for me
