I'll have to look at it when I get back to it.
You don't want to open another can of worms with MTB derailleur compatibility with your STI levers. I'd recommend chucking the whole 6800/FSA mix and buy a full GRX kit before you go throwing in MTB components.

Going back to your original post, it seems you had a bike that shifted properly but you didn't like the asymmetry of two spacers on the non-drive side, so you made it symmetrical and now the bike won't shift. So it seems that the guy who installed the crankset knew what he was doing. And If you want the bike to shift again, all you have to do is move the spacer back. Look, the purpose of the spacers is to resolve the chain line, not change your pedaling dynamics. If the chain line doesn't work, the bike doesn't work.

By the way, is your front derailleur band-mount or direct-mount?
