RFE on H1b extension after H1b transfer approved

I am working for company A and my H1b valid till Aug 2018.

Company A filed H1b extension on April 2018 in regular processing

Company B filed H1b transfer on April 2018 in Premium processing

Company B’s H1b transfer approved

After 4 days, Company A’s H1b extension got RFE

Does the RFE on H1b extension have any effect on already approved H1b transfer?
