Resistance on Kickr now not working after recent update

After the most recent upgrade my resistance on my kickr now no longer functions properly. I start on “just ride” and the resistance is a lot higher than it has been before but when I get to the first climb the resistance becomes a lot easier (kind of reverse as to what it should be). I have tried everything from reinstalling zwift to trying to change the resistance level in wahoo app to sim mode but still no joy. Trainnerroad is working fine.

Help would be greatly appreciated.
