ATEM 1M/E Broadcast Panel can't save button map

I haven't played too much with ATEM 1M/E Broadcast Panel yet but I've noticed that it didn't save my custom Button Map. According to manual I should get Save button when I make changes, but I don't. I do get it when I change the brightness of the LEDs. (I tried changing Button Map and LED Brightness and hitting Save after all of this but only LED setting got saved.. )

Is this known bug? I do have the latest drivers loaded on PC and have the panel connected via USB but didn't get any update requests?

Is there any way to fix it? Downgrade?

Any help would be nice. Thank You
