Default Filename with Save to Devonthink 3

I have long used the “Save to Devonthink3” workflow which I choose in Word under Print / PDF.

For as long as I can recall, the default/proposed filename came up as the title of the Word document. Lately however the default filename is the last filename I manually typed in Word; it does not use the name of the Word file.

Did I change some setting to cause this?
