Mismatch in ITC claimed as per GSTR3B and as per GSTR2A

Hi. We handle customs clearance and transport services. We regularly avail transport services from our vendors for which we pay tax under RCM every month. We are taking credit of this tax paid under RCM by declaring the same under GSTR3B. Recently there is a provision introduced in GST website to compare the ITC availed in GSTR3B and ITC available as per GSTR2A. Since all of our transporters are unregistred all these invoices have not been uploaded vendors in GST returns. The ITC available as per GSTR2A does not reflect the tax paid
on RCM on which credit is available. Due to this there is a mismatch between the ITC claimed by us Including credit taken on Tax paid under RCM and ITC available as per GSTR2A. Pls suggest how to solve this issue and what i should do going forward
