Fenix 8 doubles my treadmill pace

Fenix 8 Solar, all of the sudden my watch is doubling my treadmill pace. If I'm at a 10:00min/mile pace, watch shows me at 5:00min. Walking too, if I'm walking at 20:00, shows me at 10.

I've done several calibrations to no luck. Outdoor run and indoor track has my pace correct.

Would a factory reset fix this?
