Hey, as far as I know, as long your update doesnt change your CRS score nor your elegibility for both EE and AINP, you can update your profile. Which seems the case here since you're only adding an end date to your work experience, right? In this case, I think you can update your EE profile BEFORE submitting your AINP application + submit a LOE with your work history documents explaining it and you should be fine. I've seen two cases of people who made small changes in their work history in EE (that didn't affect their CRS score) and got their nomination already
