Both the preview on android and the hovercard for the web will incorrectly render a dts  template. See https://en.wikipedia.org/wiki/Melodie_(album) for instance.
Android Version 5.0, stock TouchWiz on Galaxy S 5. The web issue was the standard web version and the app version was from the app. Wikipedia app v2.0.110, and the browser was the latest stable version of Chrome for Windows 10 x64, don't know the exact version as I'm not at home atm.
Here's an image of the error. The issue looks identical on Chrome. http://i.imgur.com/Q3Qq3Nw.jpeg
