How to Tweak Profile to Keep only ENG & UND Subtitles?

I did, but it seems to have made no difference. I tested a bunch of files using (1) MKV Unprocessed profile - Default language, (2) MKV Unprocessed profile - English language, (3) rename only.

I attached a screenshot with the original files highlighted in yellow. You can see the conversion language specified in the file path.

This may be unrelated, but why is “S32” or “S24” being added to the name of the audio track?

Is there a way extract or trim a file to ~5 min for testing? I only have a few sample files & it’s headache running the conversion process on a large file only to have it not work out.
