Yep, I have a CEM70 and it does that (although not always).
No big issue for me because I setup and tear down every night. Might be an issue (or better, an annoyance) for ppl with observatory and stable setup though.
My workflow is: setup everything, staying awake a bit to check that all is working fine, going to bed because meridian flip and auto-park will take care of everything, wake up and see that parking is horizontal (even though I set vertical) and, most of the time, still reporting slewing to. Therefore I click "goto home", turn off everything, etc
Few minutes ago i powered up my new CEM70 mount. I used the pad to go to the Zero position and setted it as PARKING position.
I would do the same thing in INDI to park the scope in a position like the Polaris instead then in horizontal. Any tips to gain this result?
Maybe a useful update:. After reading this thread I just got my new CEM120 and set the Home position and a custom parking position at aprox 90 degrees using the hand controller. Then I set up EKOS with same parking position and it all works fine. I can Park and unpark from Ekos and it shows the correct status in mount control. Mount connection via ethernet. I do however have a different problem at the Meridian that I will start a new topic for.
