we were just smush

Hello, we were just smush some images, and this is what we got, at the bottom of all our pages.
" Sorry, too many files being returned. Please use filter to reduce the number."

It also, broke the link images to some social media icons, how do you recommend fixing that?
What does smush do to .jpgs that we already optimized anyway?

Only way to fix was turn of the plugin. Whats going on, can you fix?
Thx!
