V25.5 running on Windows 10

For some liturgical music I have created to fit our church bulletins, the secretary has asked me to print to a pdf size of 8.5 x 7. 

I have gotten this all set up properly it seems through Page Layout, it has a *custom* listing with the measurements listed above in it.

However, when I go to the "file: page setup" (which really is "file: printer page setup", I don't know why Help has it listed differently than my actual program), I cannot find any custom option, other than PostScript, and even that gives me no options to actually change the page size 8.5 x 7. I, myself, don't have the printer that prints to this size paper, but my church does; I am just trying to send them a pdf the secretary can use immediately without having to go through all this trouble, herself. 

I know things are not right when I go to print and I get the "page size warning" dialog box. I just don't know how to proceed. I think I figured this out a year ago, but I have forgotten completely and cannot solve it this time around. I'm printing to my CutePDFpro program as my printer selection, for what it's worth.
