Cannot Rename USB Connections to Control Multiple Printers

Just installed Octopi 0.16.0 on a RPI3 B+ running Octoprint 1.3.10. I am following the instructions found here: https://www.youtube.com/watch?v=7Saa1HpLRoM&list=PLkwzDQxW75SSdhQ_Gt_3qu_vwQMKYIJop&index=13&t=0s

I have been able to duplicate 2 instances of OctoPrint in the /etc/init file successfully and rename printers in the GUI. All three of my printers are TAZ 5s so I have found some differences in the attributes using the diff command in the terminal.

I used the diffcommand to determine the differences in the attributes on the two printers since the vendor id and model are identical. Here is the output:

I have rebooted and I still see ttyACM0 and ttyACM1 in the "Serial Port" section under "Connections".

Should I be using different attributes to identify the printers?
