Cover Note: Why does the cover note not have my correct details?

It's only the first page of the document is personalised and the rest is just a sample policy for a hypothetical flight. You don't need to specify your drone in this case. This just allows the CAA to have full detail into the cover you'll get from Flock, even before you buy a policy.

The document is CAA compliant and your actual Insurance Policies will be customised to your specific drone.
