Multiple authors won't appear in compile

I have added two authors in the compile settings (See attached image.) However, only one (the first) author appears anywhere in the compiled output. I’ve tried using <$fullname> and <$author> variables in the compile templates, but it doesn’t seem to make a difference.

Only the first author can be used as a placeholder at the moment - the “authors” list is mainly for metadata.

All the best,
Keith
