Seller Central changed language to Spanish and I can only List on Mexico Market Now. How do I fix this?

I did not touch any setting at all related to language. This happened completely out of nowhere with no reason I can point to. I just logged on for the night to list more inventory and as soon as I started I noticed every single item I was attempting to list were all on the Mexico version of Amazon. I went into my settings to see what that was about and my entire account settings section was in Spanish. I figured out how to get the settings page back to English, but most of my account is still in Spanish no matter how many times I select English as my language. I can't list anything, I can't view my inventory and I can't read anything. I have 0 items on the Mexican Market so when I check my inventory it says I have nothing listed.
