can't get any stars in workout mode

I can’t get any stars in workout erg mode.  I use a kick,  I am smooth with my cadence but im always over or under target power.   The power zones aren’t to hard for me. but im always over or way under
?

 

I lost about 600 exp today.  

I have a Kurt Kinetic Smart Trainer and never had luck with the way it estimated cadence. I bought a Wahoo Cadence sensor and things have been spot on since.
