Bug Report: Moonlight Shuriken Inconsistent Perhaps due to Adjacency to Carefree Countenance Bidoof

In a ranked game, upon using Radiant Greninja's Moonlight Shuriken attack to KO my opponent's active Growlithe with the first target, I targeted their benched Charizard EX, which resulted with no damage being marked. There was no Manaphy with Wave Veil on either of our benches, but there was a Bidoof with Carefree Countenance next to the Charizard EX. I am confident I did not place the second 90 onto the Bidoof and noted the visual of the bench barrier defense appeared on the Charizard EX.

Later in the game I intentionally utilized Moonlight Shuriken to check for a repeat targeting two benched Pokemon another Growlithe and a Charmander, this second usage both attacks were successful, however neither Pokemon were next to a Carefree Countenance Bidoof.
