I was able to export the pdf as facing pages (non-continuous), but recently discovered I am now unable to even select those options for some reason. I recently downloaded a plugin called "in5" https://exchange.adobe.com/creativecloud.details.100761.html and uninstalled it when it turned out to be a trial with watermarks. I've attempted to change one of the export options from "page" to "spread" with no success.

I reinstalled Indesign CC after uninstalling the plugin and am still getting this problem. I am wondering whether this is a software based issue, or CC account issue.
