GST regular B2B supplier uploaded bill under RCM

Greetings for the day.

My dear professional colleagues, I had a query related to getting input tax credit. In a case of my client -

Initially, goods purchased from a registered regular dealer (supplier) and paid the amount including gst amounts. 

Later the supplier uploaded the b2b invoice under RCM applicability, which was done erroneously.

We paid the gst which is auto populated in GSTR3B under “Inward supplies liable to ReverseCharge”. and also taken credit in ITC as in the case of RCM.

In succeeding month, the supplier amended the bill with RCM status as “No”. And with this amendment, in GSTR2A gst amount shown positive and negative. And also in ITC statement, the credit is reversal automatically.

Please guide me, if anyone had faced such problem earlier. 

Thank you.
