Error while saving the approval workflow

Hi,

We have created a custom approval procedure and assigned it to one of the approval level in the existing workflow.
While saving the approval workflow we are receiving below error.
[2133229] This approval policy is not valid: Error - The step 'CCC-2AF9BF2612E1B542969A15DFE6E349 - CCC-B97A49B90DD49948BC2F8B915990F - Client OwnerApproval' must be attached when compliance check exits with error.

Can someone please let us know how to fix this issue ?

Thanks
