That would be a problem. Does it says your status like full time, if so I don't think it would be a problem. But check IRCC website under work experience section to be sure.
As far as I know a typical pay stub needs to have either the hours you worked or full time or part time status. That is why usually pay stubs are requested by IRCC to prove your work experience. Though I maybe wrong, check the IRCC website under work experience for more insight.
