Layering works but, if only for this, it's an overkill.

Hint: read attentively what Mike wrote.
N.B. NWC doesn't care, but the stem direction of the 2/4 chord was wrong.

Converting that file I got the warning
"Tuplet 2/3 can't be processed.
Staff: P1/staff-2/voice-3, measure: 38"
This can be solved using this trick:
!NoteWorthyComposerClip(2.751,Single)
|User|TupletMarks.fso|Pos:11.5|span:2|number:2
|Note|Dur:8th,Dotted,Slur|Pos:7|Opts:Stem=Down,Beam=First,XDotSpace=-1
|Note|Dur:8th,Dotted|Pos:6|Opts:Stem=Down,Beam=End,XDotSpace=-1
|User|TupletMarks.fso|Pos:10.5|span:2|number:2
|Note|Dur:8th,Dotted,Slur|Pos:5|Opts:Stem=Down,Beam=First,XDotSpace=-1
|Note|Dur:8th,Dotted|Pos:4|Opts:Stem=Down,Beam=End,XDotSpace=-1

This is just for information; I think implementing it in the program is too much hassle for too little.
By the way: the music notated in NWC is attached here. No need to say that it's a joke a friend of mine sent me!
"Genetliaco" is a very erudite form of "birthday"...

It's notorious that NWC after the D.C. or D.S. does not applies the master repeats.
Well, that's one of the two "standards" and has its reasons. 
What happens with the lyrics looks instead as a bug.
I'm not one of the experts mentioned by Mike but I can suggest a workaround as follows.
