ACDX GP15 Not Reading New Proxyxml

I changed the locomotive repaints of the ACDX GP15 to read the DTG NS GP38 High Hood locomotive sounds. I also changed the BN GP15 repaint to read the GP38. I went test the sounds and the BN repaint worked but the ACDX repaints continued to use the SD40 locomotive sounds. I checked every Proxyxml and bin files to see if they were the same and they were. Would someone have any idea why it is not reading the new Proxyxml?
