I’d say your current TP/FTP is 215ish or 220ish.
The numbers are estimates of a moving target.
The FTP estimate app on the Garmin is not as robust at a post-ride analysis on XO.
That’s why you can get a BT alert on a Garmin (Connect IQ player app) or EBC on a phone, but not when that activity is uploaded to XO.

What platform is prompting for FTP in order to track it but is not able to estimate it?
