I am using Vegas Pro 12 and am trying to apply Event FX to my video clips. However, regardless of what effect I add, the clip is all affected, except a rectangle in the middle of the clip, which is left unaffected. This stays true for any video clip and any effect that I have tried. I'm assuming it's a settings issue, but I have no idea where to look to fix it. Any help would be appreciated. Here is a screenshot to show what is happening.
