Movie sets

R[/b]unning Kodi 16.1 with Aeon Nox on
windows 10.
Just installed so please excuse all my questions.
When I have films in sets and I enter the film set I see all the films, my problem is how do I get back out of the film set to carry on browsing through other films/sets etc.
On my last Kodi setup there was an arrow that I clicked on the exit the set but not now,,
Any help appreciated in advance
