Great to hear that the main issue resolved itself!
For the other issues I'd suggest you check how it looks in regular Live Channels app (https://play.google.com/store/apps/details?id=com.google.android.tv) first. If you have similar issues there it's most likely something we can fix, otherwise it's probably a Philips issue. I don't recall some of the issues you are telling me about, but then I have others instead ;) My Philips has a few years on it's neck so you'd think they would have fixed it by now...
Double description is one issue that is not unlikely to come from PVR Live (in combination with Enigma2). But please check with Live Channels first and get back to me and we can have another round of issues/fixes.
I see. The missing icon is Google's doing. Not sure if it's intentionally or by mistake, you never know with Google. Until they get it fixed you need to use a custom app launcher like this one: https://play.google.com/store/apps/details?id=googletv.livechannels.launcher
PVR Live? I though that was why you wrote in this subreddit.
