Ok firstly, on several of my accounts the address for owner, active, and memo are exactly the same address. So I'm not sure if that is proper, but it certainly prevents me from importing an active and owner key. Second the GUI lists all the owner, active, and memo addresses exactly as the CLI has them. However there is still no balance information in the GUI.
*Edit*
Ok I have found a/the problem, I went and executed a get_private_key for a key from the output of my original "import_balance accountname ["*"] true" command, it's a good thing I logged it! After importing the private key to element 0 of the array of the logged output into the "WIF key import" of the GUI I now am showing an unclaimed balance of bts. Should I attempt to do all the elements in the output array?
