iWatchTV IPTV Picons

I had installed iWatchTV IPTV on Vu+ OpenBlackhole 2.1.7 image and had all picons showing both on infobar and also channels list. Now I changed image to normal Blackhole image 2.1.7 with same skin as I had on the OpenBlackhole but have very few picons showing on iWatchTV IPTV channels. Don't have any problems with Satellites Channels' picons on both images. Picons are installed on USB. Have this problem both on Vu+ SoloSE and Vu+ Duo2. Any help will be appreciated.
