i guess you applied "Position Constraint" as your default Position Controller. thus, the object you created is also placed in (0,0,0). also, you cannot move it by Gizmos.
pls do the following steps...
1. select the object that you created.
2. go to Motion Panel (right column tab)> Parameters
3. under "Assign Controller", select "Transform: Position/Rotation/Scale"
4. go to "Position: Position Constraint"
5. select a little button under the "Assign Controller" tab.
6. pop up a window calls "Assign Position Controller"
7. select "Position XYZ"
8. press "Make Default" button on the right side.
after those steps, you can create and move you objects whatver you want. hope this help.
