Value "ALL" been imported to Cost Center through CWB

Summary:

We've just created the production environment for our client. We've created a hierarchy for allocation. This is coming from the Cost Center Value Set, and this is additional hierarchy beside the regular cost center hierarchy.

The client provided a Parent value with the name "ALL" to the value set. And because the Value Set and Hierarchies been configured through CWB, the value been successfully imported.

The issue is that we are maintaining FBDI for the COA, and we can't validate this FBDI because the value "ALL" violate the validation.

This is a major issue for us. We must have the option to have a valid FBDI for our COA. Is there any way to edit Value in the COA?
