50,000+ mint showed up in my wallet as STAKE, then disappeared. Twice!!!

I have many millions of mint in my wallet and was expecting POS to start soon, but I wasn't expecting it to disappear soon after it showed up in my wallet.
So I am wondering WTF is going on with my wallet that 50,000+ mint would show up in STAKE and then disappear.
Any ideas on why my stake has vanished from the front page of my wallet? I don't see it as transactions in received, but it sure was in my wallet a while ago right below the balance in the stake line..

Any others have this problem?
