Profile Switch when Challenge is chosen

My wife and I both have the family account. I believe that I may be the primary but am not certain on that one. Anyway, she likes to ride a challenge, whereas I simply ride.

In the last few weeks, it has come about that when she chooses her challenge rider and starts riding, my name shows up on the screen rather than hers on top of the chosen challenge rider. She has also noticed that the ride is significantly harder than it was before. She will admit to some lost fitness, but not to that degree. We have a Wahoo Kickr Smart Bike, the original edition. It would almost seem as though the Fulgaz is grabbing my weight instead of hers(225 vs 140) and she is having to push that up the hills.

I don’t know if this is similar to the other issue about switching between users, as we seem to be able to switch, but something seems off here. Thanks.
