Radiant Charizard no weakness

Rautsu

I attacked a Radiant Charizard with a Cramorant (Lost Origin) and it didn't triggered the double damage from weakness. On other instance I attacked another defending Radiant Charizard with a Radiant Greninja and the water weakness also didn't triggered on that occasion. Is this intended or a bug?

Cramorant's attack stays it doesn't hit for weakness. The instance with the Greninja, was the Charizard the active Pokemon or on the Bench? If it was on the Bench, then weakness and Resistance are not applied for Bench damage

Rautsu

The instance with the Greninja the Charizard was on the active spot.

Did the opponent also have Chandelure (033/192 RCL) in play? Its ability would've negated that weakness.
