Open Graph has issues
Open Graph tags are related to social media sharing functionality for your pages. SEO Optimizer does not create these tags in your site code, but only warns you when it sees a problem with them. Open Graph tags are created by your theme code. If switching to a different theme is not an option, we recommend getting in touch with your theme developer or a Shopify Expert to fix your theme code.
For details on what is wrong with your Open Graph tags, copy the URL of your page whose audit is showing this issue, and paste it into the Facebook Sharing Debugger.
