voice lines in medieval 2

I'm quite new to total war, I'm entering these games with medieval 2 because they always appear everywhere lmao, but oh well. I recently got into the topic of mods and I've had a problem. With some mods like vanilla beyond the voice lines are well arranged and that, but in others like roar of conquest the voice lines get messed up. The Christian factions have the voices of the Islamic ones and the Islamic ones with the Christian ones. Does anyone have a solution or know why this happens only with that mod?

and no, it is not because the game is in Spanish. It also happens in English and yes, it is a somewhat silly problem that can be discarded for 90% of the campaigns. But it takes a lot away from my immersion that my French and English knights are shouting for Allah and my Turkomans are shouting for Jesus Christ.
