I'm not familiar with that mod at all... what folders/files are in it?
Edit: you might also try sending a PM to the modder who made it, he's not posted in a couple months but might still be checking in. His profile is here:

The info on the mod says it returns the colors to the contacts, so it would just be a matter of identifying which files. I suspect it's the xxxx_shp.tga files in all the data\Air and data\Sea subfolders, does ACM Lite Map include those? If so the first think might be to delete those from the mod and re-enable it and see what happens. The .tga files shouldn't have anything to do with the zoom features for your harbors.
Best bet would be to make a copy of the original mod and rename it, then use that one to fiddle with and test in-game so you've always got the original to refer to if you go nuts and forget what you took out and what you didn't.
