I have two account types which are identical except that the code for the one is "income" and the other one is "Income". My assumption is that a module created the duplicate. I only noticed this today, and my bookkeeper has already used both interchangeably without informing me of the problem.
Is there a way of either merging the two types into a single type, or deleting the one type and forcing all invalid references to the other type? If not, how would I go about forcing the bookkeeper to use only one?
