Not a typo, actually; in this context, phrases like "I should only be a minute" are understood to mean "I should only be gone a minute." (In fact, changing the sentence to read "It's should only be a few weeks," would be grammatically incorrect. On the other hand, "It should only be a few weeks" is a valid alternative which doesn't change the meaning of the sentence too much.)
