My Export Is Longer and Different Than My Timeline


I updated into the newest Premiere Pro last night if that is relevant as I never had this issue before.
For some reason, my exporter is outdated. In other words, there is 23 minutes of footage but that is from days ago. Yet, my timeline is near only 12 minutes. I don't know what the issue is exactly or why this is happening. I tried what I can (being a rookie editor). I tried deleting cache but nothing changes.
I just want my exporter to reflect my most to date timeline. I do not have stray frames.... My exporter seems to be taking old deleted footage from the timeline and adding it somehow. I never had this problem before either.
Thank you.
