Thanks!

As you said, this is a bug, or rather a design flaw. Need to add support for fully controllable values. Right now the internal value is always updated. Workaround below but will keep this open until a fix is released.

The onChange handler is set after the value has been updated. What happens in your code is that you stop tracking the value after 2 has been chosen. What you need to do is to slice the values in your else, like this:

setValue(values.slice(0, 2));
