Some Documents have the Grid Selection Disabled in Document Format Requirement Layout


I have yet to find a pattern here, but on some of the Documents that I create the Grid radio button selection in the Document Format > Requirement Layout field is disabled.

I have the ability to change from Paragraph to Grid on 3 of my Documents (good) and I do not have the ability to change on 4 other of my Documents (not good).

Any ideas would be appreciated. Thank you!
