Sharepoint 2013 - CSOM - List Column name mapping

Hi

When i use CSOM in powershell i get all the columns in a list, the first being 'Title' which technically does not exist (anymore).

What may have been title, is called 'Area Name'

>> So how do you map FieldValues.Key to the true name ? e.g. "Area Name" does not seem to be in the keys, BUT it is the name of this column.

Thanks in advance
