The way it's described in the "knowledge base", it should be pretty easy to change the order of spouses if you don't know the exact marriage dates (but know the correct order):
"Change the families order
(Windows) Click Right on one of the spouses, then choose Order of spouses. Use the Before and After buttons to organize and click Close."
However - I cannot click right on the spouses in the single or the family view.
I have someone with two spouses, for one I have a marriage date and the other was before (I don't know if/when married) and I want to order them accordingly, but right click does not open a window/buttons/...
Did anyone find another way to do this? Am I clicking wrong

Thanks!
