Visibility of Access token after expiration


Could someone please guide me as to why the details about the access token still visible when it is expired.

I executed the following curl command and I’m still able to view the details about the tokens that were created a week ago. I am using OAuth2 plugin and the expiration time is set to 7200 seconds.

curl -sX GET http://localhost:8001/oauth2_tokens

Have I missed some configuration?

Best regards,
