I have one problem not letting me sleep at night

:'( can some experts help me?
while creating EE profile i included job A ( current job ), Job B and C ( previous jobs ) on my work history
Job B and C does not affect my points, they were temporary jobs different NOCs and do not affect eligibility of my EE profile.
After getting ITA I realized that i need to provide reference letters for All 3 jobs i have showed on work history.
I want to delete Job B and C form work history and keep it on personal history so i don't have to provide reference letters for that. ( i just have pay stubs for those jobs, cant provide reference letters for those jobs )
Is it Ok if i Delete work experiences after getting ITA?
