Lunar Blessing weapon swap bug

I put all my skills including lunar blessing in weapon set 1 exclusively and only ferocious roar is in weapon set 2:
If I activate lunar blessing after ferocious roar while still being in weapon set 2, lunar blessing doesnt proc moonbeam on any attack.

Also not sure if this one is a bug but If lunar blessing is used in weapon set 2 and I attack with a weapon set 1 skill it doesn't proc moonbeam either while the buff is active; the skill has to be in the same weapon set as the attack.
This one might be intended but writing just in case it's not.
