User Account Suspension is not working in WSO2 Identity Server 5.10.0

Have configured Idle account suspension in WSO2 Identity Server 5.10.0 using below steps:

• https://is.docs.wso2.com/en/5.10.0/learn/user-account-suspension/

• Added below configuration in deployment.toml of IS
  [identity_mgt]
inactive_account_suspention.enable_account_suspension = true
inactive_account_suspension.trigger_notifications_at = "13:00:00"

• And I am using JDBC as a primary user store in IS:

• Have configured below values under Account Management Policies-->Lock Idle Accounts in IS
  Lock Account After (days) --> 12
Alert Users before account locking in days (comma-separated list) --> 6,7,8,9,10,11

• However the above configured values are not reflecting in wso2is-5.10.0/repository/conf/identity/identity-event.properties file and it is showing default values as shown below:

  suspension.notification.delays=30,45,60,75
suspension.notification.account.disable.delay=90
  suspension.notification.trigger.time=13:00:00

User account is not locked and didn't receive email notification after exceeding defined Idle Time( last login time).
