Cisco firepower 2140 fxos interface ccs0 is down

[HHazarika]

We received an alert indicating that the interface "IF-Firewallname-FP/27 [ccs0]" on the firewall named "Firewallname-FP" is down. Upon inspection in FXOS and ASA, we found no interface labeled as 27. Could this be a bug? This issue typically arises within the first 30 days after a reload. (We are running code version 9.20.2.2).
