I had the same problem and did the workaround.
But now it only shows UIA's, not BitAssets and BTS.
I did the wallet rescan blockchain but that didn't help, I did see all (bitasset) transactions popping up though.
My second to last transaction is now on 28 February, with a balance of roughly 5* BTS what it should be.
The last transaction shows a balance of -0.1 BTS on fen 28.
