Page creation adding -2 to slug, but there is no page/post w/that trailing slug

Replies: 1

Task:
We’re creating a brand new page.
We’ve attempted to us 4710 as the trailing slug (websitename.com/4710

Issue:
We have no previous media, post, page, or CPT or anything with the name/url of /4710

When changing the slug to 4710, the immediate result in the slug area is /4710-2

Can anyone point to a reason for this?

Thanks in advance for any reply,

Michael
