Road signage says "Kilmacanoge".

Road signage alone does not mean that this spelling should be the primary/preferred spelling used absolutely everywhere, but it does back up the assertion that Kilmacanoge is the official spelling, IMO.

I updated all road-related features that I thought should match the spelling used on the road signs.

Is there anything else that ought to be renamed to use this spelling?
The village relation/label?
