perm salary? if pijiang or 863211 available?

Hi,
My PERM (EB2) was audited, now the case is still pending...
Yesterday I reviewed my PERM application again, found that the SWA prevailing salary request (level 3) is:
$79,747/year
but my offer letter's only $77000/year + $23000 bounus/year,
I contacted my lawyer and HR, they think it is an issue and they agree to change to 80K salary +20K bonus.
but I think we also need to inform Atalanta DOL for the salary correction?

Am I right? How can I do?

Thanks
