Transactions Not Showing in Block Explorer?

Hey friends,

I’ve been mining Ravencoin for about 4 months now and I have my mining rewards being sent to my wallet address in the Edge Wallet app. However when I copy and paste my receiving wallet address into the Raven block explorer it shows a 0 balance with no transactions? I’ve also noticed that the wallet address appears to change frequently in the Edge Wallet app yet my mining rewards still deposit just fine. Can anyone shed some light on this for me?
