Yes here is another person again!
I must say, the loss of Rai channel names is worse now, than how it was until recently.
Only after about half the transponder scans attempts, the correct names show up in the "Last Scanned" bouquet.
Then if I scroll down, often the names disappear immediately. And if they stay, they get lost later.
Edit: there is a workaround.
Scan the transponder until the correct names are showing. Don't press "OK", upload immediately to channel editor.
I use E-Channelizer, set these flags for the channels (there is also batch editing):
"Do not update parameters automatically" and
"Keep unchangeable during service scan".
