LTC4015 Battery discharge current is zero

Hi,

I'm using LTC4015 to charge a 2 cell 7.4V Li-ion battery. When the Input power(12V DC) is connected I am able to read the charge current and is approximately correct, but when I turn on the module with only battery LTC returns the battery current as zero(external multimeter says 13mA).  And when there is no battery connected LTC's charger status says battery short fault instead of missing fault. Can you please check the attached schematic for any possible errors(Ignore the AC section).
