Unfortunately the bug that causes the channelgroups in tvserver config - TVchannels to disappear (and therefore unable to sort, edit or add/remove channels in the groups) is still there. 
Here is the bugreport of the bug in 1.0.1:

Here are more people also reporting the problem (I did not copy all posts about this):
