New 3.40 version not allowing filename edit upon print

Hi,
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?
