Replay Editor Bug (PC STEAM)

whenever I save a file it automatically overwrites the last one so I can only have 1 clip saved at a time. But the bigger bug is that after i trim a clip and go to export it just immediately exports. So for example , I'll have a 30 second clip I want to export but when I start the export process, after 2 or 3 seconds it says Exported succesfully. And then I only have the first 3 seconds of the clip I wanted to export
