Image Optimizations on outerbanksrestaurantguide.com

Hi...still attempting to figure many aspects of creating a website. Images on my site outerbanksrestaurantguide.com needed to the optimized according to GTmetrix. I installed Smush and optimized all 1260 images. However, when I run a GTmetrix report after install and after optimization many pages still show that images need to be optimized. Here's link to GT with Smush active https://gtmetrix.com/reports/outerbanksrestaurantguide.com/IhUOHNex

Here a link with Smush inactive https://gtmetrix.com/reports/outerbanksrestaurantguide.com/S5kI0BR1
I obviously don't get it. What wrong here? Any advice is appreciated.
