There is an issue with the base MPC firmware that I thought you may be able to solve.
When using the HWP firmware the FN1 key can be pressed before SHIFT to input SHIFT + FN1 keys, when using even the base MPC firmware to input any symbols or SHIFT + FN1 shift MUST be pressed before the FN1 key as any other modifier input is seemingly ignored when FN1 is held.
No idea if there is a possible fix via this tool, figured I'd bring it to your attention.
