Fritzing is generating double routes between some parts in PCB View

What steps will reproduce the problem?
1.in schematic view place 3 resistor and 1 generic female header 4 pines
2.connect ping 1 from each resistor to the 2-4 pines in the header
3.connect the other resistor pines (number 2 of each resistor) together in the 
pin 1 of the header

What is the expected output? What do you see instead?
Fritzing creates double routes when it makes the autoroute task

What version of Fritzing are you using? On what operating system?

Version 0.8.7 (b1bf5 2014-01-24) Cocoa [Qt 4.8.5]

Please provide any additional information below.

This is only an example about how to place the parts, the original file is an 
array pf leds with its own resitor of 220ohms and a connector to another PCB
