In the store guide you use a 5 and an S in the screenshot and from a a distance they look the same, perhaps if you change it to another number it might be helpful and may save that problem.
I write it: B 10:S 5 by the way, and it works fine. If the format in this sign is correct then it seems they are interchangable.
Actually you can just put 10:5 and it will do the rest but yes I agree those are close together. I was actually considering touching up that section at some point, most people dont know that you just leave the top line blank for example.
