If you go to "Options"

For the "Texture Packs" option instead of showing Texture Packs, it shows as this "options.texture.pack"

If you go to "Video Settings..." Smooth Lighting instead says "Smooth Lighting: options.ao.max"

Under "Multiplayer Settings..."
Instead of Chat Scale it shows as "options.chat.scale: 100%"
Instead of Chat Height Focused it shows as "options.chat.height.focused: 180px"
Instead of Chat Height Unfocused it is "options.chat.height.unfocused: 180px"
Instead of Chat Width it shows as "options.chat.width: 284px"

As far as I can tell everything else in the Options menu is fine, though I have not thoroughly explored the settings

I also have the following mods installed
