Double Function keys, double Tilde, possibly more do not work

The hotkey system recognizes double key presses but often when used on unrelated commands it does not work at all. Example, tilde for all TC and tildex2 for all economic buildings does not work. Truly ought not to be the case. If the system can recognize the double keypress and lets the user assign them to separate functions, why does it simply not work?

Thank you @DeathByGuava916. This is something we are looking into. Appreciate the report!
