11.5.10.2 Treasury Bank Account Balances and CM Bank Statement Load

I am having some difficulty with the Treasury Bank Account Balances related to linked bank accounts.

It is my understanding from reading the documentation that all I am required to do to update the Bank Account Balances in Treasury is to link to the AP bank accounts and load bank statements into Cash Management.

However when I do this I am getting 0 balances displayed in Treasury. It is generating lines in the xtr_bank_balances table but the statement balances are always zero while the statement lines being loaded into Cash Management are not zero.

Am I missing a step somewhere, and if I am why is it generating these zero lines?
