Sublime Text is autocorrecting “^”

I use Sublime Text 3 for my LaTeX coding. Whenever I try to type something with a carat such as

^{x+2}

it autocorrects it to

{{x+2}}

. The autocorrect occurs right after typing the first curly brace and only occurs in math mode. I've looked through my Key Binding settings but it all looks pretty foreign to me. This post here seems to refer to adding this autocorrection, but again is tough for me to understand what is going on.
