This behaviour is used because you can't use only a part of a transaction So the client took the 0.45 transaction you received about 2 weeks ago (a9e4...), sent the donation to your 18neW..., and sent the remaining bitcoins to one of your wallet hidden addresses This way, you still have the money you own, but you don't see a useless 0.35909091 transaction in your wallet
