Channels grouping doesn’t work

Hi everyone!

OpenELEC 7.0.0 on Raspberry Pi
Kodi 16.1

PVR IPTV Simple client v1.12.14

After installing from scratch channels grouping has stopped working.

Here is the playlist sample:

Code:
#EXTM3U
#EXTINF:-1, tvg-name="0x0 Fireplace HD" tvg-logo="0x0 Fireplace HD" group-title="Развлекательные", 0x0 Fireplace HD
http://192.168.0.3:8081/channels/play?id=15260
#EXTINF:-1, tvg-name="0x0 Music" tvg-logo="0x0 Music" group-title="Музыка", 0x0 Music
http://192.168.0.3:8081/channels/play?id=15245

Looks like m3u format is correct, but all channels displayed as one long list
