Cal State Application mistake

My son submitted his applications to Cal State. He just realized he put the Spring courses in progress instead of plan. What steps does he need to take to fix this mistake. I’ve read online and we would need to contact each school via email or contact each school on phone? He applied to 3 of them. And a mistake like this will it be detrimental to their decision of accepting him for next fall 2020?

This is a minir error and admissions will be able to figure it out but for piece of mind, you can email each CSU admissions office regarding the error. Include your CSU application ID and any other pertinent identifying info.
