Pvr live TV OSD video issue

I use osmc rpi2 Kodi 18.3rc1 compiled 2019-05-19
I don’t know how to describe the issue ,but when I start live TV " pvr IPTV simple" I had the right video OSD for live TV then I can find tv logo , info and epg but when I switch to other channel I got video OSD for simple video player
The issue is not related to the skin I had the same issue with default osmc skin and other skins . thank for helping
