View Mode Reflections issue

Hello everyone, I’m working in the lighting of my scene, and when trying to see my Reflections on the scene, the View Mode Reflections just display the environment in a solid grey.

I have an Skylight, one Light Source and several reflection capture spheres all over the place, and doesn’t affects to the View Mode.

But if I apply a total reflective material to the object in Lit mode the are working properly.
