wrong TB inbox content

I have four AOL-based eMail accounts I follow on TB; let's call them A, B, C and D. The folder contents on A & C are correct. However, for some odd reason, TB is placing the contents of A's eMail folders in B and in D! I have deleted the accounts twice, closed TB, re-started, and re-added B and D accounts, but the contents still are of A's eMails?!? Please help!
