VE PRO import tracks from project issue


I just imported some VE PRO 6 instrument tracks (multi out) from a template into a small audio-only project. I immediately got spikes (real time peak). Disabling the VE PRO tracks got rid of the spikes.

When I open that template with many instrument tracks and VE PRO tracks, all is fine.
(Newest versions of Cubase 10 & VE PRO 6.)

anybody experience this as well?
