Custom view mode for entity references - getting rid of title
You could do this with display suite as follows:


Enable display suite and display suite extras (important)
At structure > ds > list > extras > Other, enable Page title options
At Manage Display > [view mode] > [layout], enable a DS layout for your view mode
Manage Display > [view mode] > custom page title, hide the page title


DS has a lot going on. But if you need custom display modes and need to hide the page title in some cases it works well. Plus you get a lot of other nice features.
