Error in citation insertion by endnote online

I’m using AMA 11th style for referencing but for some reason, the insertion shows in a weird format (see below example) and it does not add any bibliography at the end.

I appreciate your help to resolve this issue.

The discovery of chromosomal abnormalities in cancers have been described for more than half a century (Amatu, 2016, gene fusions as novel targets of cancer therapy across multiple tumour types)

That looks like a temporary citation inserted by EndNote Online.  Are you sure those are parentheses and not curley brackets?  

If you open the bibliography settings and go to the “instant formating” tab, (see attached image) does it say "instant formating is off,  and a button that says, “turn on”?
