Smart gripper doesn't show up among devices

Hello,
I've recently started using RobotStudio and I am trying to simulate how the robot can use tools, so I have imported a Smart Gripper from the Import library button and mounted it on my robot. However, I am unable to see the gripper among the devices I can define IO signals for, it also doesn't show up in my station logic.  When I go to Modeling > Layout, it clearly shows "Smart_Gripper_Servo_Fingers" under mechanisms, but when I try to edit it, there is no option to add or delete anything.
Did anyone else have the same problem?
