Grammar mistake on experience letter

[susan khadka]

I have already submitted my document and just cane to know that on my recent employment letter there was a slight grammar mistake. It should be mr. ..... is getting paid $22 per hour and the mistake on the letter is mr.... was getting paid and same on the hours aswell as it is written in past tense on the current employment letter does it matter or what can be done as it is a gramatical error
