Import V5 2017 CATProcess with more than 1 Part operation into 3D experience on cloud

I have a V5 CATProcess with 2 Part Operations I try to import into 3D Experience. When it is imported there is only 1 Part operation, with 1 setup. The second part operation are gone!!!

Is this a bug, or is it work as designed?

I could not find in the documentation any usefull info about this.
