Properties cannot be rolled

Cannot roll [+armoured +monsters ] or [+armoured +berserks] on charm for some reason. While you can have infantry with berserks and monsters.

Is it possible to roll Monster+Armoured combo on a charm?

Have an issue today rolling this stats on a charm today, spend near 150 rolls and haven’t seen this combo (but saw a lot of Infantry+Monsters, Infantry+Armoured). I’m not sure if it’s a bug, indended or just unlucky me.
