New 3.40 version not allowing filename edit upon print

In the new 3.40 Build 5156 PDFCreator it is not saving my filename edits as it has been in previous versions.
I set it to prepend the date/time stamp to ensure uniqueness and then add a descriptor.
I can enter the descriptor but when I look in the save directory it just has the time/date as the filename.
I didn't make any config changes when going to the latest version, do I need to make a change in order to allow editing the filename upon print/save?
