Hi Devin,
I'm not entirely sure if this will help or not. As I am not finding much on the problem at the moment. But something that's been said in the EA forums and Answers.ea.com. It might be due to the December patch update unchecked the "Include Custom Content" box in the My Library "Advanced" section. Unfortunately the checkbox doesn´t appear in offline mode.
So that might be something to look into?
