Category Icons keeping old domain URL

My site was on domain.azurewebsites.net when I set up the site, including category icons. When I moved to https://www.domain.com I noticed that many of my wp-contant/uploads files still had domain.azurewebsites.net as the URL. I did a search and replace on the _posts and _postmeta table to fix this and it worked for everything but the icons I use in Category Icons plug-in. They still use the domain.azurewebsites.net URL.

Any idea where that is being stored so I can change it? It’s not in wp_posts or wp_postmeta

thanks
