LT4363 3-500 uA leakage through SNS in shutdown mode

In shutdown mode the LT4363 is supposed to have 7 uA. However, if external power is supplied on the OUT / SNS pins, the leakage rises to 3-500 uA.

This leakage is rather substantial and is not mentioned in the datasheet as far as i can tell.

It is inconvenient for us because we use the LT4363 as an input protection (over voltage and over charge current) on a battery, so the OUT/SNS pins actually never goes to ground, even though we switch off the enable signal (see attached schematics)

If you have any idea of why this happens, and what we could have done to see this, from the datasheet, it would be appreciated.

Thank you,
