Somewhere above correction filter #10, MC did not want to load revised/saved config files. At 10 filters and below, no problem. Above 10 they would occasionally load...other times a complete shutdown was required to replace config files...and a few times even that didn't work the first time. This was finally identified by creating different file names for the revisions...the only way I could see what was actually loaded at any given time.
Second problem may or may not exist: Even when config files were located in separate folders, MC didn't seem to like the repetitive file names Acourate assigns, even though they are in a different folder/path...again filters numbered above 10. I say this problem may or may not exist because I gave all of the filter files different names at about the same time I figured out problem #1.
Everything runs fine now. Here is the config and channel mapping used in the solution:
