I honestly have no clue what you want me to do here.Zoroark bug. My opponent has 7 pokemon instead of 6. https://replay.pokemonshowdown.com/gen7randombattle-995546686
Yes, Zoroark makes it look like you have more Pokémon than you actually have. That's how Illusion works.
"When this Pokemon switches in, it appears as the last unfainted Pokemon in its party until it takes direct damage from another Pokemon's attack. This Pokemon's actual level and HP are displayed instead of those of the mimicked Pokemon."
Zoroark imitated the Blissey, making it look like they had two Blisseys. How else do you want it to work? Please, tell me, I hate getting this report but I have no clue what to do about it.
