Check is on the TODO?

I am getting what appears to be good test results with the exception of a message/warning. I’ve searched for a TODO setting/check but not seeing one and I’ve looked for a disabled image type. I don’t know if I have a problem or not. I’m running on SiteGround NGINX w Cloudflare.

Message/warning: “Everything seems to work as it should. However, a check is on the TODO: TODO: Check that disabled image types does not get converted.”
