There is never a need to type the file name because it's done automatically as the file names takes on the title of the news article. Under the file name is a toggle for Save as Adobe PDF, which is by default saving as pdf. FYI, If I print the web page and then choose Adobe, the web page prints but the layout isn't as good as printing the web page and I have to write in the file name using this option.
Usually the Convert webpage to pdf works and works very well but I have had this problem in the past with other versions. It's a bug I believe.
Maybe I will try repair a few more times.
