Hi, you hit a bug introduced with a refatory of view hints. The problem with the order is not that they have to be in alphabetical order. The problem is that they have a circular reference in one order and not in the other. As soon as I have a couple of hours to dedicate to it, I will fix it. Sorry for the delay.
