Default Can't select species in fuel inlet?

Hi !

I'm trying to process a 3D cyllindrical combustion chamber, where I want to inject some fuel via a fuel velocity inlet into the chamber where there is an air inlet and an outlet both being also velocity inlets at the "tops" of the cylinder and the fuel inlet being a small cube embedded into the side of the cyllinder.

However, when I try to select the species for the fuel inlet, nothing pops up, like it is unselectable. Why is this happening? I can select species for the air inlet, but not for the fuel inlet. Is it a problem with geometry?

Thank you all in advance
