Create a custom device in CatTools

I am working off of the How to create a custom device document.  I save the Custom.device.template.ini to he /Devices folder and rename it to Custom.Ericsson.ATM.ini.  I htem change the name to Custom.Ericsson.ATM under the [device] field and id to 4999.  Under the [item_name] field i change default to Ericsson.ATM.  I then save the file.  Open up CatTools and try to add a new device.  Then name of Custom.Ericsson.ATM or Ericsson.ATM does not show up.  Is the document missing something as i  am fairly certain i performed the steps a per the document.

Thanks
