Update: I fixed it.
I had Jinx, Hunspell, and Flyspell going off at the same time. For some reason, "I've" is "incorrect" in the British dictionary? I just took out Jinx and Flyspell (disabled it) completely and I'm just using Hunspell for now. We'll see if that works. I have 3 dictionaries on it: en_US, en_GB, fr (for French).
