On the enwiki page for the German Revolution of 1918–19 I'm getting an issue with the Bulgarian Wikidata language link on the left sidebar, which is displaying the link to the equivalent Bulgarian page as "1919) – Bulgarian" instead of just "Bulgarian".
I'm on Google Chrome 57.0.2987.133, and have the gadgets SidebarTranslate and "Mark navigation links to featured and good articles in other languages" enabled.
