AP Generate Electronic Payments

SOLVED

Has anyone had an invoice get paid twice using AP Generate Electronic Payment?  I paid an invoice February 28th.  after that date, a change was made to the distributions the way Sage taught me.  Reversed prior distribution entry completelety and entered new distribtuion info.  Invoice now has a credit balance which caught my attention.  This is great but i would have preferred not to give up $25k needlessly. 

Thanks for your help!
