[xwiki-users] Missing Edit options

I have an instance of XWiki Enterprise 6.3 running with no access for unregistered users. I am adding content as a user with membership to XwikiAdminGroup, which has admin and program rights across the wiki. I wanted to add a Groovy component by creating a new page and then editing the object properties, but the "Edit" button does not have a list of edit options - I can only click it to edit in the default view (currently set to WYSIWYG). I can change to the object editor by explicitly changing the URL to add the GET parameters "?editor=object". If I log in as Admin I get the usual "Edit" button, that includes the various edit modes including "Objects". Any suggestions for how I can get the same options as another user? I don't recall having this problem in previous versions of XWiki.
