Hi, I got a new windows wallet with a new address early this month.  When it was done synchronizing, it gave a balance of 4.95 Hush in a second address.  I never sent any Hush to this wallet, so I don't know where it came from.  When I just opened the wallet today, it showed a balance of 0.495 and then after it synchronized now it says a balance of 4.06838947.
What is happening?
