I am assuming you did not use a LR scanner, as the sensor scanner said it was not for one O2 sensor. If you went to an independent LR mechanic with the authorized scanner, you would get exact codes for each O2 sensor that failed.
Bottom line, you need two new O2 sensors for bank B, but I would confirm as soon as possible.
