Received ITA but have questions about Post ITA application

[sneha1409]

I added my profile to Canadian Experience class and recently received an invitation.

Some questions regarding work experience.

1. I added my student part time under work experience for only 20 hours. Does it get counted? I tried removing this in my Post ITA application and previewed the score. It didn't change. Is it safe to remove? (The problem with keeping this is I am unable to receive work experience letter from my university in the format required). So would it be ok to remove from Work History and keep this only in the Personal History section?
2. In another work experience, I incorrectly added my title. Actual title was Assistant System Engineer but I added System Engineer. How do I update this title? Is there a webform? Do I need LoE?

Safe to remove if doesn't change your score. But you will need to mention it on the personal history.
