Smart Gripper not working

Hello,

I have a Yumi and am trying to calibrate the grippers. However, when I click the Smart Gripper program on my Flex Pendant, I can click the configuration icon and turn them on, but I cannot click on the icons for the left and right grippers for some reason and am therefore unable to move them.

For reference, I am using RobotWare 6.09 and SmartGripper 3.55

Any help would be greatly appreciated.
