Captial Projects File -> new greyed out in Project Configuration area or unable create picklist and other config objects

There will be reason like

1.Permission issues

2.membership issues

3.Config types missed in Content Rules of the project config folder.

But in my case the I have seen funny and intresting issue with objectlist component which is hidden configuration.

You can not see any error messgae logs because it is not error.

In the object list component we have configured columns based on folder path for the projects like below

<scope

                                location="/PROJECTS/PTDR-ABC/04. Master Documents/01. PROJECT COMMUNICATION,

    /PROJECTS/PTDR-ABC/04. Master Documents/01. Forms,">

                                <component id="objectlist"

                                                extends="objectlist:eif/config/library/objectlist/objectlist_component.xml">

unfortunately  there was comma”,” before close scope tag <01. Forms,"> so we have remove it and system behaving as expected
