Suspend Session Icon/Button Missing

[Ninpodeshi]

I was exploring and changed my desktop background and themes recently. Shortly after, the power buttons changed when I click on the start menu button. Before, there was a power button to click on that gave options to lock the screen, shut down, log out, or suspend. Now, there are separate buttons for the power options, but the suspend session option is gone. (See pic below.)

I've changed these options several times, and the changes were only cosmetic before. It's possible, but I don't believe I did anything to make that change. Is there a way to bring back the Suspend Session option there?

Thank you.
