Cashflow validates on entity currency but not on parent currency

Hi,

I have a case where my cashflow hierarchy is validating against the cash change member in my movement dimension, however when I change the currency to "parent currency" I get differences, which I don't expect.

The steps:

-I have shared all the BS movements to the cashflow hierarchy with opposite consol operator.
-On "entity currency" my cash change member matches the outcome of the cashflow hierarchy.
-All my BS and PL accounts look ok also my BS difference is zero.

I am curious if any other user has experienced this? and if so I would like to know if I miss a config setting.
