Disney Jr. .. video question

HI, is that true that with the current Disney Jr addon.. some clips there only have sound but not video? I have almost half (or a bit more than half) plays only the audio with no video.. is that normal? or is it my setup. All those clips with audio only, it usually shows "Playing xxxxx.mp4" on the top. usually Mp4 are video files.. it makes me wonder if it is my device setup issue. But as I said.. i can play some clips no problem.

[btw, i am using Kodi 17 on Android]


thanks
