Welcome to the Insiders forum! I'm carat and I'm one of the moderators here in the community and I'd like to help provide clarity for you. By the looks of what you've provided above, these certificates seem to be Redemption Certificates for upcoming stays you've booked using points and not unused certificates. When you have unused certificates in your account, it will look like something below. If you do not have upcoming stays for these dates, let me know and I can take a deeper look into this.
