Different wallet address every time I launch Raven Core

So I just started mining Ravencoin a few days ago, I'm fairly new to crypto but I finally felt I knew enough to start mining. I downloaded Raven Core and I'm mining with Gminer in the 2miners pool. I finally got up to the 10 RVN payout but I noticed it wasn't showing up in my wallet, so I double checked my address and realized it's now wildly different from what I put into GMiner. And I now notice that every time I close Raven Core and relaunch it I see a brand new address for my receiving tab. So kinda cheesed I've been mining for nothing for a few days but I'm glad I caught it on the first go. Any ideas why this is and how to fix it? Maybe I should note that I don't think I've gotten to 100% sync yet at the bottom of Raven Core.
