ath10k: problem mac80211 tid?

Hi there,
 
I try to connection repeat test on ath10k. And I saw problem that broken(?) mac80211 TID in /sys/kernel/debug/.../stations/XX:XX:XX:XX:XX:XX/agg_status. 
 
The test proceeded as follows. 
    1. AP - Hostapd is On, STA - wpa_supplicant is On. (Connection)
    2. Confirm the connection, and keep the connection for 10 seconds.
    3. AP - Hostapd is Off, STA - wpa_supplicant is Off. (Disconnection)
    4. Repeat this. (yes... It is a very simple test.)
 
I try to change 0 at value of "wmm_enabled", I couldn't see the problem. 
 
But I want to "wmm_enabled=1", because I don't want to loss bit-rate.
 
Is my setting wrong? Or is it a bug? (Tell me if you need more information.)
 
Here my configurations and debug message. (This is a message when a problem occurs. Wifi is connection. )
