i have a "muxing" issue; i hope some1 can shed light on. i am using mkvmerge.
objective: i am looking to swap out Queen Emeraldas episode 02 with a new version
with corrected audio. in the submission the french and japanese tracks were messed up.
the audio is fixed and is illustrated by the file named "001_track3c.mka" as illustrated below.
unfortunately the VobSub track (highlighted) is missing in the newly muxed file.

now here is the newly created file:

as it appears in the encoded file:

any commentary is greatly appreciated.
