Can`t select specific static meshes inside my actor blueprint

Hi everyone, Im having some issues with my project with some actors blueprints. When on the viewport, I add a static mesh component to my actor, and when I click on the mesh I made on the dropdown menu it simply doesnt work. The mesh I made is there in the dropdown menu, and the mesh changes when I try the default meshes like the cube and the cylinder.
The mesh is used in another actor blueprint, so I know it works.
If someone knows how can I fix this it would be great. Thanks

Can you show some pics, don’t quite understand…
