Void Cloak Avionic Upgrade issues

[loop8000]

Basically when you upgrade the avionic alone it can go up to level 4 which slows you to 25% speed and gives 30 seconds or so of cloak. With grid the description of the item changes appearing stronger I.E. 2 grid makes speed 35% with 40 seconds of cloak, but in mission this reverts to the rank 4 on mouse-over and the increased effects do not seem to apply. Can you please fix this avionic so it can actually use it's full potential?
