bibliography format not working

Somehow my refernces within the paper will only show in a weird many coded {bracketed} format or with author name and date if I push “unformat” This all happened after I shared a paper with someone and they added their endnote references to mine I think. Also there is a bracket that says the reference list title but no refernce list is printed. How do I get back to my regular numbered references?. PS. Every paper that I have in my computer now has these screwed up reference formats.

see previous topic: which points to this FAQ:

 This worked perfectly. Thank you so much.
