Sudden change in citation style

I’m very new to Endnote, but I’ve been using it for a paper for a few weeks. Today, all of a sudden, the citations are always inserted as {last name, year #1}. This is independent of the style I select and editing the output style does not change anything. On the same computer, an older draft of my paper will insert a citation just fine, but I’ve made a ton of changes on another computer and now the working draft won’t cite correctly. Any ideas? Thanks!

The instant formating has been turned off – you can easily turn it back on and update the citation and bibliography from the ribbon or toolbar.  which version are you using?  

The 2013 ribbon locations for these options are attached.
