Lab 9.3 - question on editing of 'configmap coredns'

Hi- When editing the coredns configmap for the second time in step#12 I was presented with a word wrapped 'Corefile' section, with a bunch of newline characters '\n', instead of being on separate lines. This made it impossible for me to complete the task without copying the text and putting into notepad++ using YAML format, and modifying it to look as it is presented in the lab guide.

When first editing this in step#8 it went into edit mode without any '\n' characters, with respective statements on their own lines. This word wrap only affected the 'Corefile' section. Hope this makes sense. Is there a way to get the editor to 'not' present these '\n' characters and instead present it as shown in the guide as initially seen in step#8. This isn't a show stopper as I got through it, but it was a pain.
