You can promote packages to testing without a valid bugtracker (unless the package system has been altered recently to prevent that) but it will be promptly rejected by testers, as having one is a requirement to pass testing.
I'm not sure why else you'd be missing the option to promote the package though.
About the lack of bugtracker, your current debian/control file uploaded with the current devel version seems not to have an xsbc_bugtracker field specified, if you add this it should show fine.
