Job title correction on the job offer letter

[Ellie80]

Hi I am preparing to apply for sinp in June. And I have a serious problem. I started my job in a hotel since November,2018. But In January, Sk government required to send all the employees' job offer and Work permits to them. I sent my my job offer letter and work permit. On my job offer my job title is a Front desk manager with $16 wage an hour. However, I found that I must be paid minimum $20 an hour as a Front desk manager to apply for Sinp. I would like to correct my job title from Front desk manager to Frony desk supervisor ($18 an hour) on my job offer letter when I apply for job approval letter and sinp. Because my employer will not pay me $20 an hour. I am really afraid to be reject sinp because my job title is different from the job title I submitted in January when I apply for sinp. Please help me.
