Traduzione - Spagnolo-Inglese - Lexicografía

What I understand reading the source text is that:
- Problems appear before adding terms.
- Solutions are needed before adding the first term in the catalog.

But I think the translation only gives the first idea. It's not clear that the solutions have to be found before dealing with the term list.

Hi, could the elimination of the comma between "arises" and "just" give the sense indicated by Isildur__ in the second point?
