Wavelab 10 elements "trigger Cubase/Nuendo update"

hi, I have Cubase Pro 11 and I’ve been trying the exchange with Wavelab 10 elements.

I can get Cubase to render and send the render to Wavelab. However after doing the edits the “trigger Cubase/Nuendo update” remains greyed out. The other icons in that ribbon, save, undo etc have gone from grey to a lighter grey showing they are now available. I’ve tried highlighting the audio, not highlighting it, Cubase 11 open and Cubase 11 closed. Nothing seems to work, “triiger Cubase/Nuendo update” remains greyed out and unresponsive to click or right click.

Can you sort your last sentence a bit? Don’t know what you mean…
