DesignCapacity() is correct but FullChargeCapacity() is incorrect

Hi,

I am using a BQ27421 with a 120 mAh Li-Ion Polymer battery. I am programming the Design Capacity to 120 mAh and the Design Energy to 444 mWh using the TI CC2541. After programming, the DesignCapacity() reads correct (120) but the FullChargeCapacity() reads 240 mAh. When I do a full discharge and charge cycle, StateOfCharge() only reaches 50%. Please let me know what I may be doing wrong. Thanks for your help!
