Videos can be corrupted, or for other technical reasons (that we'll go in detail later) videos can't mix together without affecting the final product video or audio speed.
Issues with Olive

Bad video files
Video 1
Video 2
This happens because all video editors like olive asume all videos have the same settings. It can't work with different settings so the program stretches the audio 1 or video 1 to fit audio 2 or video 2
