So I think what I would do in your situation would be to see if after a week things leveled out (pounds gone again?) If not I would temporarily remove nuts but keep eating 30 carbs for the next week to see if your body is still fine with that much carbs.
Once you have figured out if you can still lose with 30 carbs try almonds again, if you get the same result you know almonds are an issue for you.
You're lucky with the peanut butter then. Keep it that way. I am somewhat obsessed with the stuff.
