It’s a bit difficult to see exactly what needs to be done, but basically I think the reason those two pages are there is that the ‘Default’ master pages are set to show all flows, and those flows haven’t yet appeared in the default frame chain that comes from the default master page. I think that if you edit the ‘Default’ master page and use the flow filter to remove those last three flows from the list of flows that will appear on the ‘Default’ master page, that should take care of it.
