How to delete a sport profile... Permanently?

For some reason I have 2 Hike profiles named Hike & Hike(2) in my F6Pro.sports list. I haven't created the Hike(2) profile & want to permanently delete it from my device but can't find a way to do it.

I can add/remove it from the active profiles on the watch & can Install/Uninstall from GCM it but that doesn't remove the profile completely, it is still listed as available to add back to the device.

If I connect my F6 to a computer & delete the Hike(2).fit file it gets recreated when I disconnect.

I've seen some threads suggesting that there should be a delete option in the profile setting but there isn't one for the Hike or Hike(2) profiles, which suggests the device thinks that both profiles are 'built-in' profiles, which can't be deleted

Does anyone know how to delete it permanently? Cheers
