Help me uninstall Miirgui

[Halona]

I posted on the addon itself but there's no activity and this is negatively affecting my raid experience.
Some of the textures are leftover after deleting all the folders in interface and deleting the addon folder, and it's saved variables file. The main thing causing a problem is my chat bubbkes inside instance being completely opaque. I installed Aurora also to try to overwrite the Miir stuff, my chat bubbles outside of instances are taken over by Aurora but inside they remain Miir textures.
