EditVoicePack Problem

EditVoicePack 2.1 has a voice file included for "Piedmont", but some of the voices in MSFS plays it back as "Mont-pied". I created another voice file for "Piedmont" and it played correctly in EdtVoicePack in all the voices. I unchecked the voice file in the Standard Modifications for "Piedmont" and installed my voice file, but it still plays backward in the sim. What do I do to the voice file to make it play correctly in MSFS? I've created many voice files and I've never had this happen. I even tried using the "force variation" option, but it still won't work.ThanksRay
