Unable to assign status schema to a document type

i just created some status schemas in IMG and went into 'Project Administration' to create some document types. i went under the 'Project Standards' tab and clicked on the 'Document Template' button as advised. However when i create a new document type and scroll right, i dont see the column where i assign the Status Schema to that doc type. all the column exist (Global, Several, Blueprint Relevant etc. ) but the column for status schemas is not there anymore.

would anyone know why i am missing that column. is there a setting somewhere to make that column visible again ?

Thanks
