Odd Permalink Structure

I’ve built an ecommerce site for a client using the Divi theme, Woocommerce and various other plugins. I recently noticed some random letters after every page. For example the home page is [ redundant link removed ] but what’s displayed is this .

I’ve gone through all the plugins, disabled them one after another, changed the theme, checked the permalink settings and I cannot figure out why this is happening. Any ideas?
