Can you post some screen shots illustrating the problem?
What version of Premiere Pro?
We want to shorten this footage as you can see in the next screenshot.
Here you can see that the footage with the drinking lady is shortened so logically it is not showing at this moment.
Here we see our preformer in his next shot.
However one frame further (see screenshot 3) the lady somehow shows up for one frame.
Deleting the whole scene and putting it back in place doesn't work. The lady keeps showing up.
We are editing in Premiere Pro version 6.0.0
Is there another track above those tracks?
Expand the tracks and look closely for a lone frame.
No there's nothing above. Even when i expand and look up closely..
Maybe an old rendering cache file? Try to delete the rendering file in the sequence menu…
