Can't set custom refresh rate on second monitor RADEON

[kecap]

I've re installed windows 10, previously I can set custom refresh rate on both of my monitors (both on 1920x1080). But right now in Radeon settings I've specifically set Display 2 to display 100hz but the settings can only be applied on Display 1, Display 2 only goes for default refresh rates (60, 75, 120, 144).

 

Radeon ver 19.9.2

2 monitor set to extend.
