Completing a workout on a trainer

Hello! I have connected my garmin edge to my Kickr Core trainer. Two questions:

Question 1: I connect my training peaks account to garmin. The workout I want to complete shows up on my calendar on my garmin. I go to trainer->smart trainer-> follow a workout. It does not have my workout from my calendar available. I choose a very similar workout that is available. I think it's my workout for next week, no idea why this one is showing up, but today's workout isn't. Where can I find today's workout?

Question 2:  I start my ride, I can feel something off with the resistance. I see my workout power zone as 155-178W. I expect erg mode to kick in so I can maintain this power. However, instead when I get close to my power zone, I feel the resistance decrease. It's like the trainer wants my power around 100W. I can't get up to 155W for more than a couple seconds no matter how fast I pedal. Why is the erg mode not pairing correctly to my workout?

Thank you!!
