Dietrich IV/VI "Nust", Graf von Kleve - This whole Dietrich von Kleve family is a hot mess

I've never been so confused before, Has anyone seen a tree-graph that shows everyone (yes, I know Geni has one, but its tree-graph generation is itself a hot mess). WikiTree seems to do a good job, but I have to wonder if anyone is really certain. The usually clear Medieval Lands is a hot mess too for this family.

I am waiting for my brain to stop hurting on this to see how Geni has it worked out.
