Heatmap Theme – WP Super Errors

I added wp super cache and wp minify plugins to increase website speed. I get the following errors related to my heatmap theme. I’m getting an “E” from YSlow and Page Speed. Both list these pages. I have no clue how to change the expiration time. I set an expiration time in super cache, but apparently it does not apply to these pages.
