I am not sure if this has been reported yet into the bug base since i can't access it from windows (don't have the pass etc).
So, the problem is that when i tried to enter a worker compound i own, it was not displayed on the list of entity i could choose.
So after setting myself as manager/operator and also added me into the crewlist, problem was the same.
Yeah the enter entity list is bugged. Usually one entity is listed there, but if there are more they are hidden further down because there are a heap of extra line breaks between the enter and kick passenger buttons on the first entity. There should be something like a 3rd scroll bar to the right hand side, nearest the middle of he screen. Use that to scroll down and the other entities should be there.
I had that same issue, and the above worked for me.
