My understanding of "edit queries" is that they would be "inquiries for revision" / "proposte /richieste per modificare/ emendare " (il contratto). According to Webster's Dictionary, "to edit" means "1. to prepare for publication by selection, arrangement and annotation; 2. to revise and make ready; 3. to govern the policy of (a newspaper or periodical); decide what is to be printed, etc." A "query" is "1. question; a point to be answered or solved; an inquiry. 2. doubt." You didn't ask, but, I'm not sure what CFRa would be, especially in this context. "CFR" in law means "Code of Federal Regulations". "CF" can mean "cost and freight". Neither abbreviation seems relevant in the context above. I hope this helps. Good luck!
