Change of title while working on H1

[drsaqib191]

I initially joined the institute as Research Associate and my H1 was filed and approved with this title. Later the institute changed my title to Project Manger, sort of promotion and salary raise. Do i need to modify or refile something with my H1 or it does not matter if the salary or title is changed while you are staying in the same place? Please advise.

Thank you.
