Railgun stuck in cloudflare

When I transfer a website away from Siteground, I noticed that the Cloudflare connection still has this SG RAILGUN notice inside:

How do I delete this ? There is no option to delete this from inside of my CF accoount?

I tried removing the domain entirely, and re-adding the site back to CF, and it just keeps showing the same?

Did you Disable Cloudflare at Siteground before you transferred your website away?

Or try from the API:

There are API calls for Account and Organization Railguns, but first try the above to see if this one shows up on your list.
