Group masters and pages

Hello,

I have never really used Group Masters before as inhibits and now i've had a play with them on the Hog 4 i'm a little confused.

I am trying to set up the console so that if I change page, the Group Master will remain effective in the background, and I will then gain live control of a different Group Master on the new page.

Currently, when I switch pages, although the console remembers the fader level, the master effectively behaves as though it's at 100% until I return to the page.

I have tried the setting "leave in background." This works for cuelists but not for group masters.

Am I doing something wrong?

Cheers
