ZWO AM5, ASI AIR Plus: Polar Alignment

Just a question:

when I'm doing the polar alignment with the AM5 using the ASI AIR plus, using the All Sky procedure, I noted that the AM5 is not tracking. 

I was thinking that after the third picture and after plate solved the mount should track?! Something not correct? If I goes into the mount setting the tracking is off and if im turning on it will automatically switch off..

Someone else has the same? 

Thanks and CS
