Hi LukePGM,
One possible solution I found was to add a SetAllPhysicsLinearVelocity node after you release the component.
You should have the variable for the Physics Object that is picked up set already. So you just have to plug that in. You will need to CastToPrimitiveComponent for it to work with the Linear Velocity node though.
Make sure to post back to let me know if this works for you.
