Bug: Name of activities recorded by a renamed profile doesn't match the profile name

I copied BMX profile to Unicycle, and recorded an activity. I expected to see Unicycle as activity name but it's called BMX. Is this a bug or are my expectations from Garmin too high?

update: I think it's a new bug, because I just checked and my "Physiotherapy" (copied from Strength a year ago) is called Physiotherapy. On the other hand I also have Walk Indoor copied from Walk and it's recorded as Walk. So it looks like a bug in some activity profiles (I guess in some the name is hard coded, while in others it's left empty so it uses the activity profile name)
