Changing project tempo causes fader levels to drop

Cubase

When I create a new project in C8 from a template and change the project tempo, the fader levels change. I have VCAs in the template. Is this a bug?

I removed the VCAs from the template and all works as it should. Guess I’ll have to keep using group channels until the VCA issues get ironed out.
