Kodi 17 krypton on raspberry

hello, I wanted to make a clarification, with kodi program in my channel list in pvr iptv simple client there are movies on demand that if I wanted to move forward is not possible, practically if while I see movies on-demand should ever lock I’m forced to see the start and i can not get to where it was blocked, this only happens with movies of my playlist channels, does not it happens with movies i watch with on-demand stream
