\ tested with Iceweasel 38.7.0 on Debian 8, Firefox 45.0 on Fedora 23, Chromium 49.0.2623.87 on Debian 8.3 (64-bit) **

Reproduction steps

1. Go to "Actors" section in CUI: https://demo2.corroborator.org/corroborator/#tab/actor
2. In list of actors, click on one actor in whose box you can't see the "involved in n incident(s)" string.
3. The "involved in n incident(s)" string appears in the clicked box.

   Expected results

Information on the number of incidents in which actors are involved should be always visible, or in alternative, it should be only visible in the box of the actor that has been clicked last.

Actual results

The "involved in n incident(s)" appears in random boxes and in those that have been clicked, but don't appear in some that haven't been clicked.

Similarly, in https://demo2.corroborator.org/corroborator/#bulletin each bulletin shows how many bulletins are involved only when clicked. After which, the information remains visible even if one clicks on another bulletin.
