BQ34Z100-G1: [CHG] bit of Flags can't be cleared

Part Number: BQ34Z100-G1

Dear Support Team,

I try to complete the learning cycle with my BQ34Z100G1 but it does not work, because the FC bit is never set. I narrowed the problem down to that the CHG bit is always 1 so the condition for the FC bit are not reached. But when i try to lower the charge voltage values it still didnt change anything on the problem. 

Are the any other ways i can force the CHG bit to be cleared so the FC bit can be set and i can finish the learning cycle?

Best Regard,
Florian
