Anyone get any advice as to how to troubleshoot this one? All seems to be working ok apart from the inverted peak the wave forms.

hi,
your Saw is the problem,
the discharge time is to long - and because of that you have the peaks in the tri and sine wave.

so the good news: your waveshapers are working

you "only" need to investigate why the discharge takes so long

Thanks very much for that, will have a poke around next week and see what I can find.
