Is OPT extension affected if I have no payroll?

I am currently on my OPT period and planning on filing my OPT extension next week. I have worked on 2 short term projects till date with pay and both projects had less than 20 hrs/week. So, typically on my 12 month OPT I have never worked more than 20 hrs/week and my consultant did not run any payroll. will this affect my OPT extension? or will my OPT extension be denied?
