[Gameplay] Fiora Ultimate Doesn't Deal Damage

While playing in ARAM as Fiora, her ultimate does not deal damage. The item I had was ravenous hydra. There were three instances where this happened. The first was when I used her ultimate on Fizz, who had his partners near him. Fizz reacted by going into stasis with Zhonya's hour glass. The consecutive hits after Fizz went into stasis did no damage to surrounding champions. The same thing happened when I used Fiora's ultimate on Chogath. He did the same thing as Fizz did, went into stasis, and the surrounding champions took no damage. The last instance was when I used the ultimate on Fizz and he used playful/trickster. After the initial hit, the nearby champions took no damage. The consecutive hits landed on Fizz and Chogath first, then went to the other champions; however, after they used the items or abilities, the damage was canceled for all hits.
