Watts set on 1999W

Hello,

Just started using Zwift with a tacx flux s and I run into 2 problems:
I can only start riding while I am also connecting to Zwift companion, but I am not moving when I only connect as ‘Power’ device to the tacx flux s.
Furthermore, when I am using the Zwift companion app I get stuck at 1999W.

Anyone any ideas how to fix this?

Thank you!
