KODI 17 Slideshow problem

Hi,

I am an OSMC user and yesterday I upgraded to KODI 17 Krypton (the official OSMC update). I just find out that with KODI 17 I can only do Slideshow of my whole source (all my photo) and not a single folder like in KODI 16.
Let me explain. I have a folder:
/media/KODI/FLICKRFS

where inside I have a folder for each event. In Kodi 16 I went in Pictures->FLICKRFS (where FLICKRFS was my source for the folder above) and I could see a folder for each event or vacation. I entered in a folder and clicked on Slideshow on left menu. Now this is not possible anymore. If I click in a folder the Slideshow menu does not appear anymore. I can only do Slideshow of the whole source. Why?
