After adding a site, i see strange A-records?

Hello,

I want to protect a site with Cloudflare.
But after adding, CloudFlare scans my site for DNS-records and comes with a lot of strange a-reords?

How is this possible?

A part of the list:
apps
app
assets
agent
bbs
beta
dashboard
download

And so further…
Have I never created all these DNS records?
How come?

Maybe a bug?
I have removed my site in CF, and added it again. And now i see my normal A-records.
