Excluding image by parent class not working

Hi Gijo…I need to exclude images from loading from the CDN because of an incompatibility with Smash Balloon’s Custom Facebook Feed Pro. The image itself doesn’t have a class, but he parent does (“sbsw-item-avatar”) so I’ve entered that into the “Exclude Keywords” field (both with and without the “.”, but it still continues to try to load the image from the CDN (which fails). What am I doing wrong?

How it’s configured: https://www.dropbox.com/s/re3n4l6l57jpboi/Screen%20Shot%202021-08-18%20at%201.46.44%20PM.png?dl=0
