It doesn't sound like there is a bug here. Have you set the in/out point as desired in your source clips? It's possible you somehow ended up with split in/out points; audio is longer than video. Check your track targeting. Refer to this page in the documentation Make precise edits using source patching and track targeting
Thank you for replying and linking this article. It does appear that audio for the entire original clip has remained on all of my clips, which is very strange considering the audio was removed before I even cut it.
However there isn't really a solution on that page. I still don't understand why I can't drag multiple clips without it forcing the audio in when I can for individual clips
