Random layer odd behaviour

Is anybody else getting strange results with the keyzone layers set to random?Sometimes it behaves strangely and it’s as if it randomizes once then just keeps repeating the sequence.

For instance its really clear to see when you do this.New instrument that contains 2 samples of a hi hat,keyzones are layered and it is set to random.Instead of truly being random it is just switching between the two samples in a consistent manner,every once in a while the sequence will change slightly but it quickly moves back to the cyclical pattern.
