Chicago 17th Footnote: removing unwanted comma

Hello,

I am using ENX7 and Chicago 17th Footnote for a paper. There is a book that I’ve been quoting several times and that therefore must appear in its short title form in later footnotes. 

The issue is: I just need the short form of the book title to appear, and do not need to quote any specific page. Endnote, however, keeps adding a comma after the short title, whereas I need to have a full stop there. See example below for further clarity.

How it appears now:

See Libro de la oración ,. (with unwanted comma–highlighted by me in red–after short title)

How it should appear:

See Libro de la oración. (without comma after short title)

I have the same issue with the Encyclopedia reference and in general with short references in which I do not need to quote a page number, but just the reference itself:

How it appears now:

See Bonora, “Quinzani, Stefana,”.

How it should appear:

See Bonora, “Quinzani, Stefana”.

Please note I have tried editing the style by moving the commas around in the book short form, I even deleted them altogether, but this comma doesn’t seem to want to disappear. How do I solve this?

Any help will be hugely appreciated!

Thanks!
