Summarize your bug The two options "SWITCH WEAPONS (TOGGLE) /..." and "FIRESTORM - EQUIP SIDEARM (DOUBLE TAP)" can not be set to an independant key. Leads to: If you want to use e.g. 1 for primary, 2 for secondary and want to use double 2 for secondary in firestorm, it wont work out because when you press "2" it will first perform 'switch to secondary' and then directly 'switch weapons (toggle)' so you are back to your primary Also there is no option to rebind weapon keys as gunner in a tank (only as a driver but you don't have access to weapons as a driver in firestorm)
