Bug report for RM Bridge

When I want to copy spring from one node to multiple nodes in RM Bridge Modeler,

e.g.

Modeler -> Segment -> segment1 -> select node 1 -> in node 1's connection tab, assuming there is a spring element 101

I want to copy this spring to node 5, 9, 13, 17, I select spring 101 and click "copy spring" button, in the pop-up window,

I put as follows:

From point: 5

To point: 17

Step: 4

Connection Point: CP01

Element: 102

Step: 1

I would expect the result would be:

Node: 1, 5, 9, 13, 17

Element: 101, 102, 103, 104, 105

But RM bridge shows:

Node: 1, 5, 9, 13, 17

Element: 101, 102, 106, 110, 114
