display won't stay on for more than a minute on my galaxy s6 active

[AC Question]

it's set for 5 minutes and when I hit ok it says set for 1 minute and only stays on for 1 minute

you probably have an app with admin rights that forces timeout to 1 min. usually some corporate email accounts do that.
settings, lock screen and security, other security settings, device administrators
