Frames are added to end of my clips

[EburgGuy]

Describe the bug It's adding empty frame(s) to the end of my clips. They play fine in the timeline, but when I export them, there are extra frames. It does this with every clip I've tried. I've tried exporting, using online tools to trim the frame(s) off, uploading it to OpenShot again, and no matter where I trim it, the extra frame(s) remain once I export it in OpenShot. It doesn't matter how long the clip is. I've tried playing them with different players and the problem remains. If I export anything from OpenShot, this happens.

Steps to reproduce the behavior:

1. Export an MP4
2. Play it

Expected behavior No added frames.
