Working hours on work experience letter

Hello everyone I have received the ITA and have submitted the employment reference documents from 2 organisations . The certificate from first organisation where I worked for more than 3 years ( satisfying the criteria to allocate me work experience points ) has mentioned me as a FULL TIME employee . However , the certificate from my next organisation where I worked for about 2.5 years only details out my job title with responsibilities and not my working hours . Will there be a problem?
