Software Version 12.70 not showing up on Garmin Express

Hi,

When plugging in my watch to Garmin Express on version 7.26.0 it does not find my Forerunner 970 update 12.70.
I can only find the update through the watch settings, why is it not showing up in Garmin Express?

Not a huge issues by any means, just an annoying one.

Thanks,
