How to create a new document using an existing template

In the former version, I can create a new document using an existing template with the following procedure:
File - New - Templates. This displayed a dialog for selecting template to be used.

In this version, File - New - Templates displays Template organizer dialog, and I found no way to use the selected template.

Using left or right mouse button or enter button has no action. Selection does not remain. I mean, after I clicked on a template and move the mouse from this template to another, the selection disappears.

Maybe you have first to activate a subset of templates (‘My Templates’, e.g.) by doublecklickking it. Otherwise please name your version and your OS.

Same here in LibreOffice 4.2.7.2 on Trisquel Linux 7.0 (~Ubuntu 14.04).
The choice of ‘file → new → templates’ (or, alternatively, Ctrl+Shift+N) simply opens the wrong dialogue, i.e. ‘managing templates’ instead of chosing a template to start from.
Although I can chose a template by doubleclicking it, I cannot reach a choice via keyboard, and it is not the expected behaviour.
Unfortunately I cannot name the update from whcih on this feature disappeared.

For @pepposz the hint to choose a container by doubleclicking first, worked - as it does on my system. The chosen setting of a template container should persist over close/open LibreOffice. If not, there might be a problem with the user profile (lacking write permission e.g.).
