Invoice number sequence in AR

I want to have the same sequence number for invoices coming from OM and manual invoices form AR.

I have created transaction types, which will automatically create categories:

manal invoice for AR

sales invoice for OM

credit manual for AR

credit invoice for OM

I have then assigned all the four categories to the same sequence: Invoice1

I have linked the transaction type in OM with the right invoice source and receivable transaction type.

Now, invoices coming from OM are taking the right numeration from the sequence.

Manual invoices instead are still taking the source number numeration instead of the sequence numeration.
