ReFx Nexus and Renoise

Strange behavior of ReFx Nexus in Renoise.
In Cubase, I have a several banks imported in Nexus and everything is working fine.
In Renoise I see only a some of them.
Can you help me?

Because Cubase is my main DAW, I am not going to reinstall Nexus and the banks (from Renoise) to risk it wont work in Cubase than.
Thank you

Have you tried manually import the banks using the banks option in Renoise or Nexus? or aren’t those .fxb files?
(Perhaps somebody else with a nexus configuration could add some 2 cents to this discussion.)
