The preference of "Render Solar Shadow" cannot be saved

The preference of "Render Solar Shadow" cannot be saved....
I have three computer with Stellarium 0.12.0

Both three computers, the config.ini file
flag_render_solar_shadows = true

Only one computer enable Render Solar Shadow on startup, but I cannot save the option that disable it on startup. Although I changed flag_render_solar_shadows = false manually, the stellarium still enable it on startup

The other two computers disanable Render Solar Shadow on startup, but I cannot save the option that enable it on startup. Although I checked that flag_render_solar_shadows =true, the stellarium still haven't enable it on startup

Seem Stellarium 0.12.0 ignore flag_render_solar_shadows in config.ini
