Named selection body doesn't show up in Fluent Boundary conditions

Hello,

I am new to CFD simulations, I am trying to do a wind turbine simulation. I drew the blades in gambit and import the file in Workbench design modeler. I then drew a cylinder (rotor) around the blades and englobed everything in a bigger cylinder representing the fluid (wind). I used Boolean to substract blades from rotor (without keeping the blades) and the rotor from the fluid (keeping the rotor).

I meshed it and named all faces and bodies.

In Fluent, boundary conditions, I find only parts related to the Fluid and contact-regions + some walls created by fluent. I can't find the rotor (faces or bodies).
I need the rotor body in order to plot the moment, drag and lift forces to calculate the Cp.

I will attach capture screens of the geometry, the named selections and boundary condition.

What's "pales"? There are two surfaces b/w the rotor and the fluid in Mesh, one for the fluid and one for the rotor. Seems strange that you can calculate the moment without the blades...

"Pales" are the blades (it's in french)
