 With the PowerPro you do not need to use a programming track, and will have better results using Ops Mode (main line) programming.  Program them one at a time.  You can give them the same address, or different numbers and then create an Advanced Consist.

If these are factory installed sound, it's an MRC decoder which are known to have many programming problems.
