Warp Stabilizer CS6 scales down last frame

Hey,

Every time I add the Warp Stabilizer in Premiere Pro CS6, it auto-scales the footage, except for the last frame. It just changes to 100% again, so I'll just have to cut it off. Any others experiencing this issue, or any ways to solve it?

Thanks in advance.

Edit: turns out it's probably not the warp stabilizer, but the position. When I adjust the position, the same thing happens, and since the stabilizer changes the position, the position will probably be causing the issue. Keyframing is disabled.
