It's not possible to close the real Gripper via movit.rviz motionplanning. Since the preset "closed" position is 0.83 and the joints are limited to 0.775. The closed should be lowered or the limits raised.
[I use custom tips, for my project, so I don't use this values and have no preferred solution]

<group_state name="closed" group="gripper">
        <joint name="finger_joint" value="0.83" />
