I'm on version 3.15.1+181017 and found a couple of bugs.
First one is when I choose to change conditions for a question, the conditions menu appears and then I select any of the "previous questions" questions and nothing appears in the "predefined" area at the right, I can switch between several questions (that, obviously, had answers predefined in them) and nothing appears in the "predefined "area". I found a workaround for this that's going to "Go to question" drop-down list at the top-right of the page, switch to another question, switch again to the one I was at and now everything works as expected.
Second one is a design flaw, when I'm in a matrix(numbers) question, if I go to the "edit subquestions" page, the Y-Scale title appears ok but then the X-Scale title appears very close, almost glued to the "Predefined label set..." button and also very close to the next row of info.
