Staking Rewards Not Sent To Correct Address

We have been staking RDD for a few months and three different rewards have been posted to our transactions list in the v3.x wallet UI. The staking rewards are sent to the following address: RwtX7ikUzKKUdMErKDZLSmWMe9kKXD1pzq but this address is not in our Sending Addresses or Receiving Addresses list. Where did these RDD get sent and is there something we need to do to get this corrected?
