IIRC, I remember hearing about a restriction on the Mod that can be slotted. Make sure you are trying to slot a Gold mod, and not a purple, blue, or green one.

Thank you for your answer. Unfortunately you can not put any kind of Mod, in fact performing the double click (or trying to use the assigned button to enter on the mod panel) nothing happens.
