Bug with Supercharger + Hardened Armor?

[S2000Gan]

If you put both Hardened Armor and a Supercharger on a mech the record sheet only subtracts 1 from the supercharger run speed in parenthesis and not the base run speed.
For example:
A mech with walking speed 4 and hardened armor has a running speed of 5, which SSW prints correctly.
A mech with a walking speed of 4 with a Supercharger has a running speed of 6 (8), which SSW prints correctly.
However with both SSW prints the running speed as 6 (7) instead of 5 (7).
