Margin orders displayed incorrectly 0.4.12

[pendragon3]

I installed 0.4.12 and it seems that some of my margin orders are displayed incorrectly.

For example, one of the orders has a much smaller BitUSD cost and collateral amount than it should (the numbers look fine when I start the wallet, but after a short while they refresh and just duplicate erroneously those of a different margin order that I have).

Also, a short transaction of mine that filled earlier is missing entirely from the list of margin orders (it was definitely not removed by a margin call or paid off).

Are these known issues? Has anyone else had these problems?
