No EQ-curves in Channel Settings and MixConsole

Hi All -

I am now tearing my hair out a little on this one - I have removed and reinstalled Cubase 8 Pro twice now, checked and updated drivers, trashed preferences back to factory settings, removed Novation Automap - and I am STILL unable to get the EQ curves to show in either the Mixer view or the Channel Settings view.

Has anyone out there who has experienced this issue (and I suspect there are a few) successfully recovered back to normal Mixer and Channel View EQ curve performance ??

Just re-iterating - if I use the Studio EQ plugin it performs fine, likewise with the Voxengo Curves plugin…

For completeness I am running :
