Mismatch - Experience Letter Degnation and PERM title

[G3SH]

Hi All, I recently resigned from Company A and joined Company B.Company B is doing my GC filing.They have started my PERM process.PERM Title is "Technical Consultant". I received an experience letter from Company A where my designation says "Manager".Basically I was doing a technical architect role and managing offshore team.However the job duties match mostly. Will I face any problem at I140 stage because of the designation mismatch ? Kindly please let me know.I will also be consulting with my lawyer soon.Anybody with any knowledge on this kindly share. Thanks in advance !
