Slideshow shrank

I’m still a novice with WP, and I manage to have my website up and in working order. Today I updated my pulug-ins these evening and now all the slideshows on my webpage shrank down to a thumbnail size.

I’ve tried the Gallery>More Options settings, and nothing has changed and is accurate to what I had before. I can’t get the slideshow to display in a normal size. Th slideshow is working, but just displaying in the thumbnail size. What am I doing wrong?
