Query: Fine, Broad, and Broad -- where's the Medium nib?

I want to learn calligraphy, and I bought this set because its price point is right for a new hobby. Today I cracked open the box for the first time, wanting to use the Medium nib, because I figured that was a good thing to start with. But it wasn't there!! I have two nibs of the same size, both labeled "B" (for Broad?) and one labeled "F" for fine. Does this mean my set was used?? Beware: you get what you pay for.However, to my untrained eye/hand, the pens do seem to work nicely.
