Adobe Premiere Elements 14 exports videos out of sync?

Hello,

I have never had any troubles with Adobe Premiere Elements 14, but I have recently run into quite a few of them.

I have been trying to edit .avi video files together, and I critique it to look good. Inside of the video software, the video looks exactly how I want it: the audio, music, and video all line up seamlessly. However, once I export it, the video clips are trimmed completely differently: the parts that I cut out play, while the parts that I want to play are cut out. The audio and music are unaffected, but all of the video is messed up.

The finished video isn't particularly long, only about 2 minutes, so this comes as a surprise to me. I have never had this problem before, and some google searching has showed that not many people have had this problem.

I just don't know where to start. Any feedback is greatly appreciated.

Thank you.
