When pressing the + icon, the "add this term" dialog opens. When pressing the + for a different term (or the same term), a second dialog opens. I request that the old one gets closed when the new one is opened.
There is a weird bug that I've been seeing because I was moving terms between schedules, and I didn't want to close the dialog. It seems that sometimes the add/remove doesn't do the right thing (removes when it should add or vice versa), and very occasionally does add/remove for the wrong word. When trying to repro the issue, closing the old dialog always seemed to make the bug not happen.
And an explanation of the bug, trying to move terms from schedule 2 into schedule 1.
1. Press +, check schedule 1, uncheck schedule 2.
2. Press + for another term, attempt to check schedule 1, but instead of doing an add, it does a remove, keeping the checkbox unchecked.
