Cheque number not be picked up by payment Journal

Hello ,

I have a payment journal and I try to post some payments of type cheque . When i try to post the payment i am getting an error message that the journal cannot be posted because the cheque number is not specified. On the bank account that i use to pay i set up cheque number and my cheque is of type fixed but it is not picked by the system. I am missing a step? Thanks for your time and help.
