This happened to me as well
The render bar was set correctly above the files of interest. and the files had unique names.
I tested with 5 clips, 1,2,3 were similar and placed into the timeline directly from the media list. I trimmed clips 4, and 5 using the media preview pane (sorry not exactly sure what it is called) when I entered them into the timeline.
The render output folder contents after render was file 3,4,5. 1 and 2 were missing. I think both overwritten by 3.
I then went back to the timeline, and made small trims to 1,2, and 3.
Reran the render, and all files were there.
Feels like a bug to me.
