H1B Ammendment for mistakes in Job Role

[manoje2007]

I got H1B approved mail and when checked the I-129 form, the role mentioned was wrong (mistake from Attorney's side).

 

But the job responsibilities mentioned in the I-129 was correct as per my current role.

 

Also in LCA , they mentioned the job role wrongly (instead of Systems Analyst mentioned as Senior Tester).

 

If I file amendment, whether it would affect my approved H1B petition in anyway (revoking/denial)? 

 

Also i heard that if only role name changes and there is no change in the duties and responsibilities mentioned, then no need to ammend the petition. So I am confused in this. Please advice
