Knowledge Check components way out of proportion

I am working in a non-responsive module and proceeded to put in knowledge check slides.  When I did the size of the components of the multiple-choice was much larger than the slide.  The "submit" button was way off the slide and the text was much larger.  I made no size changes to the project or to the slide in question.  This has never happened before.  My other modules have never had this problem.   The attached screenshot image is at 100% which I normally work in on my large monitor. Thank you in advance for any ideas why this is happening.
