Vent doesn't work for Bixby set level commands

Devices & Integrations
1

I’m happy worker working with SmartThings.
The mobile device is a Galaxy S9 (SM-G960N) and the Android version is 9. The SmartThings app version is 1.7.60.23.

I have two questions about Devices > Voice control documentation.
I confirmed that Vent power on/off works in Korean on Bixby.
However, the fan speed set level did not work with Bixby.

  1. How do I say the speed value to adjust the fan speed using Bixby?
    Values ​​are auto/low/medium/high, but examples are numerical. How do I order Bixby?

  2. If the device name is Korean, can SmartThings work with Bixby?
    Can SmartThings recognize Bixby commands even if I have a mix of English and Korean?

Thanks in advance,
Best Regards
