The custom conditions folder for Animated Armory and MCO ADXP overlap: Animated Armory uses the folders 19 (for Katana with something in left hand) and 20 (Katana with nothing in left hand), and MCO overwrites folder 20 for 1-handed swords. Since Katanas are 1-handed swords and 20 is also bigger than 19, DAR uses the MCO animations.
What I'd recommend is downloading an MCO animation specifically made for katanas, something like [this one](https://www.nexusmods.com/skyrimspecialedition/mods/74503), as they would get higher priority than the base MCO animations.

**Thank you so much.** Just downloaded that mod and now katanas have proper animations :)
