There is a small typo in the key plugins.generic.dataverse.settings.default.authorGuidelines, of file plugins/generic/dataverse/locale/en_US/locale.xml
If you’re hosting from the stable branch on github.com, then you’d just pull in the most recent updates. Otherwise, you’ll have to either patch it manually or wait for the next stable release. We use git to manage our hosted installations, and it’s very useful for keeping everything up to date.
