Why doesn't my signature show up?

I debate this in my head frequently. AN is only supposed to be used before a word starting with a vowel. An egg, an electric buggy, a buggy, a thrashing. An RC is technically incorrect, but sounds better. If I have learned anything from the English language, it is that rules are not followed. How about I before E except after C, unless you are spelling science.
