OpenText 24.1: Workflow Scripts > Projects Scripts > Common scripts is not editable. Unable to add content to it.

Hi, 

We just upgraded from ALMQC 17.1 to 24.1, and unlike ALMQC 17.1, am unable to add scripts under Workflow Scripts > Project Scripts > Common Script: 

17.1 and previous versions of ALMQC Screen:

24.1 Screen: Am unable to add any content to the Common Script/Requirement Module Script/Defects Module Script: Its not editable. It has to be configured anywhere? Atleast in 17.1 and previous versions, that wasn't the case. Please advise. 

Any help would be appreciated. Thanks.
