How do I change screen lock options when it says it's disabled by admin?

[Note4newbie]

I've been trying to secure my Note4 and I untrusted some credentials, and encrypted phone and then after seeing that my chosen password was way to complex to enter every time I turn the phone on, I decrypted to see if I could change my lock screen entry to a swipe mode. Everytime I enter screen lock settings and at lock screen the only option is password. All other options say they've been turned off by Admin, encryption policy or credential storage. Do I need to trust my credentials again to access different screen lock options? I'd like to access pattern or swipe.

Welcome to Android Central! I always thought that encrypting a device was irreversible. Encrypting the phone requires you to use either password or PIN to unlock.
