[Gameplay] Ekko's taunt for Janna bugged?

So today me and two friends were checking out some of Ekko's champion taunts for in a custom, starting with Janna and the taunts for Zillean's Ult.

When Ekko taunted Janna it wouldn't play the taunt directed at her, instead playing the ones directed at Jayce instead. I'm not too sure if this was a one time thing or if it truly is bugged seeing as we never got the chance to test it again, only being able to make sure it actually was the taunts for Jayce.

No skins were being used and Zillean was on Ekko's team while Janna was solo.

It was more as if Janna's taunt wasn't there to begin with, as some of the times Ekko would use the taunts for Piltover champions. This doesn't concern me all that much since I don't play Ekko, but I'm curious as to if it was a bug on my end or other.
