Also, in your first image link, you'll see a button labeled 'Move Selected Device to Top'

In the box above this you'll notice MIDI Mapper is above the MS GS Wavetable Synth
You'll also see the error message mentions the MIDI Mapper setting.

Clicking that button will move the MS Wavetable Synth to the top of the list.
This alone fixes many issues.
Not only is it now selected to use, it is assigned the default slot.
I guess sometimes it matters whether it is in the default slot (not just selected). MIDI Mapper is rarely the best choice in Windows.

NEXT:
In image your 5 all MIDI channels are assigned to the same patch (Piano - 1)
Click on the desired MIDI channel and select a different sound.
See my image below. Click arrow at bottom left of your track, select Edit VSTi, and select a patch for that MIDI channel. I'm about to select an electric bass patch for MIDI channel 2 in my image.
