LINX Servo trying to control multiple servo motors. Arduino UNO PWM pins 3,5,6 not working??

[rcard53762]

I am trying to control a 6 servo robot arm with LINX and an Arduino UNO. 

While using the Arduino PWN pins 9, 10, and 11 everything works OK.

But when I try to use the PWM pins 3, 5, or 6 the program errors out and I get the following message. 

Servo Close N Channels.vi<ERR>
The specified Digital Input channel (11) is not available on the . This device does not support Digital Input.

Is there something different with the Arduino PWM pins 3,5,6?

I attached the Lab view vi. 

The Lab view code is exactly the same except the servo number is different inside each event structure.

Any help would be appreciated.
