Creating a Roll over budget

Summary:

Hello,
I have COA of 8 Segments. Out of these I don't want my budget on S3 only (Region).
To achieve this, I added a tree to roll over my budget on Region when definint Control Budget.

Purpose:
I want to add my budget in system with the following combination

01-0000-0000-0000-110011-00-0000-000
Where S3 being Common value of region.

Error:
Segment values in control budget segment Region are invalid for this control budget because they're either undefined or at the wrong level. (XCC-675208)

Confusion:
I've done the exact same thing on a different server a while ago. It was working there but not here.
