Screen Recording won't record the right size screen

I have tried multiple times to record my screen and it will not record at the size I need it to be.  I am doing the step-by-step recording and want my "clicks" recorded.  I also have a "master slide" with Information and Main Menu on that slide.

1. When I record (custom 960 x 595) to have the my master slide fit, it doesn't show the master slide.  The recording is the size of the slide.

2.  When I select the size I want to record and click on record, it records smaller than that.  Meaning it records the area I want recorded, but the entire screen.  I've attached what it looks like.

3.  When I record "full screen" it records smaller as well and there is a black area around the full screen, as well as the "red" recording area.  I've attached that as well.

I need a step-by-step recording that is that specific size so it fits in my master slide and the video.  I'm using a 960 x 720 story size.  I should say that I've done this before.  I'm actually making edits to an "old" course and the screen recordings on the old video worked, but now it doesn't.  I've attached the file I'm working with as well to show you what I need.

Can someone PLEASE help me?

Thanks,
Heather
