Rush does not render vignette settings

Just began using Rush yesterday! It's a nice little program, but obviously a huge memory hog. Very laggy. The final rendered videos play well thru QuickTime and on my Android phone. 

One strange bug: vignetting settings DO NOT RENDER into the final video. I've uninstalled the program, etc and tried saving the file three times. Each time it's the same, vignetting settings not applied. 

Anyone have this issue and a solution? The program should not have this very obvious issue. Come on Adobe, get your programs working!
