Bug - for RDS Aurora, it shows 2 lines for the same instance

This happens when I select Aurora MySQL or Postgres.

e.g. https://cloudprice.net/aws/rds?filter=db.r6i.2x&databaseEngine=Aurora+MySQL&databaseEdition=&licenseModel=No+license+required&timeoption=hour&columns=InstanceType%2CInstanceFamily%2CProcessorVCPUCount%2CMemorySizeInMB%2CProcessorArchitecture%2CPricePerHour%2C__SavingsOptions%2CBestOnDemandHourPriceDiff&deploymentOption=Single-AZ

And then on the instance page, it shows 2 different prices for Virginia!
