Campaign Search does not seem to return results in the body of SCHEDULED emails

I was searching for an email about a particular topic, and my search contained no results. Upon further investigation, I realized that the search results did not contain any results when only the BODY of the message included the search words, if the email was SCHEDULED. It DID contain results if the words I was searching for were in SENT and DRAFT emails. That seems like a bug to me, has anyone else seen this? Thanks!!
