I had the same behaviour yesterday with 1.82, but only on one client out of four.
Furthermore, every startup of editor he loses more or less names, and it seems to be that only the first 16 channels are not recognized.
Probably it has something to do with the java version, because the clients run different versions…

Solution with renaming one channel functions except the channel coloring.
Second solution for me was the import of channel names tool (Tool cuts down the names down to five characters).

I will investigate that during the next days:)
