I can't apply two or more rotation behaviours like pitch and roll to the same target component. The model jumps around and behaves weirdly.
The DS Rotation behaviour only works with one data value at a time, and you cannot target the same component with two rotation behaviours.
The solution is to create a parent for the target component in the object hierarchy in the details panel, such as an empty component. Target that for one axis with one behaviour (e.g. for pitch value), and then target the original component with a second behaviour (e..g for roll value).
This should in the desired behaviour i.e. the target component appearing to move for both the pitch and the roll values simultaneously.
