If you use the following categories it will make these medals black and not red.

I also did a search on Fold3 and found the information on the date he was listed as missing in action (12 Feb 1951) and disposition date (31 Dec 1953). The following was listed as a comment
"Corporal Justen was a member of Company C, 1st Battalion, 9th Infantry Regiment, 2nd Infantry Division. He was listed as Missing in Action while fighting the enemy in South Korea on 12 Feb 1951. He was presumed dead on 31 Dec 1953. Corporal Justen was awarded the Purple Heart, the Combat Infantryman's Badge, the Korean Service Medal, the United Nations Service Medal, the National Defense Service Medal, the Korean Presidential Unit Citation, and the Republic of Korea War Service Medal."
Hope this helps you with your further research.
