Manual check posting ignore bank code

SUGGESTED

I assume I have something set up wrong to cause this but I can not find where.  I am using a single user desktop Sage 100.  When posting manual checks, the bank code is ignored when the Daily Tran register posts to the GL.  The check history report shows the checks 'posting' to bank code A and B as entered but the GL posting actually goes to bank code a GL account despite bank code B being set to the proper GL acct.  I'm not using divisions.  Any ideas?
