Can confirm, will fix.
It's a silly mistake on my part to be honest, I set a localised_name on the base game's inserters (Fast, Filter, Stack and Stack filter) to change their names to express, THEN copied the base game inserters (as a starting point) to make turbo, which copied the localised_name tag.
The fix would be to either add the localised_name tag AFTER copying them to turbo, or set the tag to nil on turbo.
