Grove modules on TI MCU CC3200 only work on one port

I have a TI CC3200-LAUNCHXL with a grove boosterpack for sensors. I have updated CC3200 firmware and everything setup. When I used analog modules, it only get the correct reading when I use J6 (pin 24). The other would make it have an incorrect reading, usually 0, on every loop. Does anybody have that problem or am I the only one having this problem. Any help regarding to this issue is great appreciated.
