Updated PDFCreator and merge doesn't work?

Hello,

I'm running on Windows 10 Pro Version 1809.

I updated today from PDFCreator 2.5 (I think?) to PDFCreator 3.5.1
I know that's a pretty big jump.

With the new PDFCreator 3.5.1 I can't seem to figure out how to make the merge function work. I can see the merge button when I print something. When I print multiple files I see a small number in a circle on the merge button showing me the number of documents in the queue. But when I actually click "merge" it just prints each document one by one separately. And where is the screen I used to use to rearrange the print jobs into one document? I can't figure this out at all. Please help!

Thanks,

J
