Can someone help me with the Argo Routing billing?

I saw this in the billing, which said I have Argo Routing enabled for my domain. However, I don't see it as enabled at the same time from the menu. It billed me 5$, so I canceled it through the subscription menu for now.

Can someone from Cloudflare help me understand why I was seeing Argo Smart routing at the same time I didn't enable it?

Thank you.
