When I render my video, a different clip shows up

When I render my video in Blender, there are two clips that play a different clip. But when I am editing the video (before rendering) I see the correct video playing. There’s no extra video clip overlapping, because when editing it shows right one.

The clip actually plays a clip before it (about 10 secs prior), so the rest of my video and text are skewed off by 10secs. Now I can’t see the last 10 secs of my full video after rendering
