THETA API Usage

I’m testing theta z1 with gphoto2.
There’s a problem with the white balance label(many unknown values).
actually, this is similar to the previous shutter speed label problem.

before

root@teevr-NucBox5:~# gphoto2 --get-config /main/imgsettings/whitebalance
Label: WhiteBalance

Choice: 7 Unknown value 8004

Choice: 10 Unknown value 8007
END
