FTP Manual Entry bug with 18.22 update

When my Forerunner 955 received the 18.22 update,   this FTP metric showed up among the data visible when I tap the Performance widget in addition to the VO2 Max, lactate threshold, and race predictions . My understanding is that this is a cycling metric. I've never logged a cycling activity with this device and I've never manually entered any FTP number. Also, FTP is blank in my Android Garmin Connect app. Anybody know why I'm seeing this?
