[BUG] TCAS TA/RA automatic checklist not working

[killerbee123]

Every now and then when the FO runs trough the before takeoff checklist it calls TCAS - TA/RA without switching it on. I have a joystick switch bound to CCP1 ATC button i use to swtich between on and off.

Hello, 

Are you allowing the FO to carry out the checklist himself or are you pressing advance checklist to go through the items?
