This took me hours to find and fix…wanted to make me pull my hair out, but like I said i figured out how to do it.
Go to the editor, make sure you’re in the stylesheet.css
Go to the section called 2.7 images
find this part
/* Add fancy borders to all WordPress-added images but not things like badges and icons and the like */
border-radius: 0px;
box-shadow: 0 1px 4px rgba(0, 0, 0, 0.2);
add in a /* before border and a */ after ; so it looks like this
/* border-radius: 0px;
box-shadow: 0 1px 4px rgba(0, 0, 0, 0.2); */
This worked for me. Good Luck!
