it's a bug that's been fixed in the later versions. Use the latest BETA version 2.3.14 and it should work fine.
Regarding your bonus, there's no "blank" profile per say but with some effort and creativity you can make one using the "copy" encoder that essentially does nothing more than copy the original file. You can set the destination directory to the source and
it'll basically copy it back onto the original file and you can keep the artifacts like the EDL and SRT and XML files.
Make sure you're using the latest 2.3.14 BETA for this type of blank profile operations since I recently fixed some issues for another user doing something similar which would prevent accidentally losing the original file.
If you don't have the patience for that use the VideoToolsUpdater software I've put, SubtitleExtractor within it. but it doesn't monitor only batch processes.
