Images resizing to wrong size

I’m having a problem and I’m not sure if it happened with my last update of Genesis, of WordPress or with something else. Every image in my slider after a certain point resizes to 920×400, no matter what I set the slider to. My blog is https://embracingimperfect.com/

You can see that the 3 or 4 most recent have that problem, while the old ones set properly. Currently the display settings are set to 740 max width and 480 max height. Any help appreciated! Thank you.
