Ubuntu Kylin Bluetooth keyboard pairing issue

[Impact]
It is common for people to use setting user-interface to pair bluetooth devices including keyboard, mouse, and etc. In some cases, when using a bluetooth keyboard which requires entering “pairing code” on the keyboard to pair, the pairing code can not display correctly on the UI interface like the attachment shows. However, by using bluetoothctl a command line tool to pair the keyboard the pairing code can properly display on the terminal. Thus, there may be some problem with the bluetooth UI interface, which is bothersome for normal users.
