Images still there after cutting (razor tool)

Question

I've used the razor tool to cut out some frames from a single video track.  This creates two tracks, which I've pushed together. I then applied the video transition affect cross dissolve.   I noticed that only in the dissolve, the cut frames were bleeding through some how.  After removing the dissolve and expanding one of the two video tracks, I can see the cut frames are still there.  The razor tool didn't do anything different than if I had just manually compressed the track (grabbed edge and slid back).  I can't find any info in the help about this behavior.
What am I doing wrong that these frames are still present?

Great news!
Once one has fought Handles for the first time, it will become second nature.
One thing that also throws people is when they have used the Razor to "cut" the Video. In the days of film, if one used the splicing block, the Frames were physically cut off. With an non-destructive NLE, like PrPro, those Frames are NOT cut off. They are still there in the source video in the Project Panel, and what one has on the Timeline is but a set of instructions. Add the Transition and the instructions are rewritten to read "OK, he needs more of those Frames for his Transition - go get 'em."
Now something else, very similar, that can be a tripping point is when one Trims Clips, Exports those as an AV file and Imports then into another Project/Sequence. All Handles are now gone, unlike having used the Razor. They are no longer there. This is something to consider, if one is Exporting for later Import, or if they are using the Project Manager, and choosing to Trim Clips. If any later editing will be done, involving Transitions, then use the option to Include Handles.
Good luck,
