I've just come across a variant of this, where the ui-select boxes are in a panel that can be hidden (but starts visible).

We've jumped from 0.12 to 0.17.1, but I don't think this is an entirely new issue. We've always had trouble with multiple ui-select boxes on the same page, and the width of the input/placeholder panel acting strangely (seemed to clear up after the various ajax requests on the page completed and angular completed another digest cycle).
