Same problem here folks. Can't really do much as Jamba and/or Isboxer keeps making a very strange Team list, and seems to kill any type of team communications, as well as other functionality.

I've seen CharacterName-ServerName
SameCharacterButNoServername
ToonNumberTwo
ThirdToon

And also seen [NO NAME/BLANK]-ServerName {or some such)
OtherToons, etc.

Not really enough functionality for me to play my teams right as of now. Wish I had a way I could help get things figured out, but my coding skills are ancient now...
