Glitch in the system regarding Resistances

While using the grizzly MK.2 Without any modules equipped under shield, I have 20 resistance, when I equip an EM-Diffuser Mk.2 Which has 39.6  resistance, my resistance DROPS to 19.6…  This is the issue

Its a known bug as far as Im aware. 

Yup, because there is a hidden “-” in there.
