It appears Garmin still hasn't resolved this issue. Yesterday, I did my first ride with Fenix 7X connected to a Keiser M3i via a K2pi PROm and my FTP updated to 239, however when I checked my FTP history, it showed my FTP went from 223 on May 14 to 494 on May 15. This is especially interesting as I didn't do a cycling activity on May 15!!! As others have indicated, it looks like I'm going to have to wait a year before I can actually see my real FTP history. PLEASE GARMIN, fix this bug, plus allow users to edit the FTP history values for any future miscalculations in your system.
You can correct your ftp in your device. See link below. Although I havnt been able to delete historical values. They are so annoying.
