Sound + Subtitles ISO disappeared after conversion to MKV

[nolensvolens]

I have a very serious problem with a downloaded blueray/DVD? ISO image
converting to MKV. I use it in PLEX which does not accept ISO.
The ISO file displays well with sound and subtitle using Laewo Blue player,
but after converting the file with MAKEMKV to MKV format, the sound and
subtitles have disappeared completely using Laewo player and also in all
other players. I am using the latest version of MAKEMKV v1.8.11 on
Windows-7 (X64), displaying the MKV-video in the PLEX-server revealed
the problem! By working backwards I pinpointed the problem in MAKEMKV.

The information of the image is as follows:
