Runpod, no calibrate option

Hi folks, noob here. I do not have the spanner beside the runpod to allow me to calibrate it. I’m running Zwift on a Huawei media pad running Android 7

I tried installing Zwift on my phone running Android 9 and I get the same, there is no spanner option to calibrate the runpod

Ok, can a mod mark as solved. My treadmill was added as speed device. Once I removed that and added the runpod instead I got the spanner to calibrate
