renaming sub-team leads to UI confusion and inability to leave channel

running keybase 1.0.31-20170917003451+ed4bf6a71 on arch linux
i created a team:

[~] ▶ keybase team create wkray_test_team1                                                                
Success!

i then create a subteam:

[~] ▶ keybase team create wkray_test_team1.subteam1                                                       
Success!                                                                     
                                                                                                          
NOTE: you can administer wkray_test_team1.subteam1, but you won't see its files or chats                  unless you add yourself explicitly with `keybase team add-member`.

then i add myself to the team:

[~] ▶ keybase team add-member wkray_test_team1.subteam1 -u williamkray -r admin
Success! A keybase chat message has been sent to williamkray.

at this point the UI is now showing that i'm a member of this subteam. however if i rename the sub-team:

[~] ▶ keybase team rename wkray_test_team1.subteam1 wkray_test_team1.newteamname

the UI still shows the old name, even after restarting the application fully with run_keybase

if i create a new channel in the subteam after renaming it, both subteams show up in the UI as separate teams in my sidebar, each with its own set of channels.

[~] ▶ keybase chat create-channel wkray_test_team1.newteamname newchannel
Success!

if i attempt to leave the team from the CLI with either the new name or the old name, i receive an error:

[~] ▶ keybase chat leave-channel wkray_test_team1.newteamname general                                    
▶ ERROR server conversation TLF name mismatch: wkray_test_team1.subteam1, expected wkray_test_team1.newteamname
[~] ▶ keybase chat leave-channel wkray_test_team1.subteam1 general                                        
▶ ERROR You are not a member of this team (code 2623)

with two channels now, i cannot simply rename the team and leave the general channel:

[~] ▶ keybase team rename wkray_test_team1.newteamname wkray_test_team1.subteam1                         
[~] ▶ keybase chat leave-channel wkray_test_team1.subteam1 general                                       
▶ ERROR server conversation TLF name mismatch: wkray_test_team1.newteamname, expected wkray_test_team1.subteam1

and even after renaming and attempting to leave the secondary channel, i have clearly broken something:

[~] ▶ keybase team rename wkray_test_team1.subteam1 wkray_test_team1.newteamname                         
[~] ▶ keybase chat leave-channel wkray_test_team1.newteamname newchannel                                 
▶ ERROR server conversation TLF name mismatch: wkray_test_team1.subteam1, expected wkray_test_team1.newteamname

Reproduce the sequence using the keybase team create, team rename, team add-member, chat create-channel, and chat leave-channel commands, then inspect the team sidebar and channel state. Done means a renamed subteam appears only once in the UI and leaving its channels no longer produces a TLF name mismatch.
