Lightbox + Whitebox + Microsoft Edge FIX?

Site URL: http://www.potterdairy.com

For some reason lightbox is not working in Microsoft Edge Browser. I used tnypng to shrink them down. I’ve tried everything I can think of. But I can not figure out why a Whitebox fills the screen instead of a zoomed pic like it does on every other browser. Is there a fix? Is this an old boring question? Trying googling “Squarespace + lightbox + white box” and see what good It does. Please help. It works perfectly on my Mac and on my phone and on chrome. But edge does those white box thing and it’s making me pull my hair out?! Why just in Edge?
