from document it´s not clear what type of route are direct route. For me aggregate routes pointing to null 0 are static routes and not direct routes.
I have two nexus Border Leaf conected via EBGP to 2 PEs. Every nexus has aggregate-routes for fabric IP configured in bgp and redistribute direct inside the BGP too. The problem is that in one Nexus I see not only agrregate route pointing to null but agrregate route from another Nexus that generate loop for traffic that dont have host route /32.
Is it the same aggregate? Can you post an example of the aggregate at site A in your scenario and the other route you are using from another Nexus and then also the /32 you are referring to and where that lives i.e. at site a or b or something?
