Apple Logic loops, copyright issues?

Hi, i recently did a soundtrack for a short film. I included in a couple scenes some royalty free loops from Apple Logic (which i own and use as a music composer/producer). I’ve heard some complaints recently of people using royalty free loops and getting hassled by previous users of the loops who have copyrighted their work. Are there any precautions I can take to guard from that?
thank you,
