Decoding a Clubs.fit file?

I have decoded other types of FIT files with FitCVSTool, but the Clubs.fit file is not decoded correctly.

Is this possible or is this type of FIT file "special"?

I have a big Bertha 7Wood, and only this club has an error in the club.fit file(or someware???) . My S42 can see the name, but when i connect the sensor it comes up as unknown. I have reset S42, deleted the club on the mobile and on the Garmin home page, but the result is the same. Once in Garmin App version 9.?? (android) it worked fine for a few days.
