A difference in accounting between the primary ledger and the secondary ledger

Hello, I created an account rule in SLA to override on the project segment. The rule is applicable on the primary ledger, but it is not applicable on the secondary ledger.

I already added the segment in the hierarchy of the secondary ledger.

This is the primary ledger, the project number appears: TS20222

This is the accounting of the secondary ledger. It always gives me "0000000" by default, and the account rule isn't working.

Please advise. Thank you in advance
