Letter K instead of number

I was just looking back at the queery that i posted of an entry in my great uncles service records. The one about the Camp or Company that he was in when he went to the Kinmel Camp for repatriation. I'm wondering now if the word in his service record is "Concentration Camp"? I found the war diaries for the Kinmel Park Camp and the headings indicate that Kinmel park was called a "Concentration Camp". Kinmel Park was not a Concentration Camp in a conventional manner but was used as a demobilization camp.
Ive sent an example of the headings from the war diaries.
