Why is my stay showing as both booked and unbooked?

I'm currently ending the first day of my first dog-sitting visit! As I put the pup to sleep though, I can't help but notice that while it shows up as my active stay and is on my calendar! However, in my inbox it and the messages still exists with a "book now" button and says "until the request is booked or archived, you may not appear in search for these dates."

Is this normal? Should I click archive or book? Would that respectively affect the status of the active stay or double charge my host?

Any answers would be appreciated!

Thanks!
