EndNote weird referencing style


My Endnote referencing has gone weird and I also lost all the reference list after I updated it for restarting error I had. So my word document restarted everytime I added a reference and looked for help online. Followed prompts to “convert citations and bibliography” to fix restarting issue. This issue was fixed, however it led to other problems like i lost my whole reference list of research articles plus I nowhave flower brackets for reference and my Bibliography duplicates with a limited number of references.

So confused.

Help please.
