difference between the two is displayed in red.
5 To reset the attachment point to the object’s pivot, reattach the object
to the Spring. Alternatively, if you click the Align Spaces To Each Body
button, both attachment points will be reset to their respective body's
pivot.
To align the parent and child constraint spaces:
1 Ensure that the constraint is selected in one of the viewports.
2 In the Align Spaces To group, click the button for your chosen alignment.
You can find out more about the alignment options in the

Child Space At this sub-object level, you can select and move the constraint
space for the child object, including the point relative to the child where the
Spring is attached to it. When you assign a child body to the Spring, the Child
Space attachment point is set to the child’s pivot point. If you alter the position
of the attachment point, it maintains its new position relative to the child
during the simulation.
Parent Space At this sub-object level, you can select and move the constraint's
second attachment point. If the spring is two-bodied, then this is the point
relative to the parent where the spring is attached to it. When you assign a
parent object to the Spring, the Parent Space attachment point is set to the
parent object’s pivot point. If you alter the position of the attachment point,
