Change of status for the class

Hello Greetings,

I have put a class status as Locked and now not able to release. Class type 300.

I am not seeing the class status as released and when i try to make ti to preparation i see this below message.

Change of status from "2" to "0" not allowed
Message no. CL046

Diagnosis
You want to set the status of an existing class to "In preparation". This status is only allowed for a class if it is a new class just being created.
Procedure
If you want to disallow the class for classification or selection, set its status to "Locked".

Have any one faced same situation.

Br,
