Do you have a cog on there right now? Have you flipped the wheel to check if its off? Should be pretty esay to visually see or measure. Does it causes any problems? Excessive noise etc.
Second, which way is it off? As lpg stated you maybe able to put a space behind the cog.
As its a brand new bike and if the chainline is off and causing problems, then wherever you bought it from needs to fix it for you (esp if it came with the cog or you had them install one). Its not unreasonable to expect a brand new bike with a flip/flop rear hub to be usable in both combos.
My mouthy opinion on this:
