ESP Modular Controller

I have an ESP Modular controller on a Xeriscaped yard with only two zones. Zone 1 does the small patch of grass, which can only be watered during certain hours on Friday. Zone 2 does the drip irrigation for the Xeriscaped plants, and can be used anytime. I have set up program A for watering the grass only on Friday morning. I have set up program B for watering the drip areas on Monday, Wednesday, and Friday evenings. However, the programs do not both run. Only the program which the slide selector indicates will run. I thought the programs would stack and all run, no matter where the slide switch it positioned. I can go through and review the programs, and the on/off days are correct, and the start times correct, and the run time correct. The rotary selector switch is on auto. Does anyone have suggestions as to what I might be doing wrong.
