I'll have to look at it when I get back to it.
A mountain bike derailer doesn’t usually play nice with road shifters. I’ve moved spacers on lots of bikes to use mountain bike cranks with road derailers. It works and it doesn’t cause problems, so why not? As an added benefit, it drives the OCD crowd crazy, so that’s a plus.
The solution to your problem is to swap the spacer back. It worked, why not just live with it?
