I installed the 11.2.4 update per the instructions on our single ZCM 11 primary server first, and then to the devices. The update installed successfully. However, when I view the System Updates tab on the ZCM Configuration page, Update for ZENworks 11 SP2 (11.2.4) still appears under Available System Updates.
Also, the update appears under Deploying System Updates as follows:

Update Name Start Schedule Reboot Behavior Stage Pending Successful Failed
<the 11.2.4 update> Per Device Per Device Selected Devices Stage 0 <all of them> 0

When I click any of the devices, the device status is Update Completed and the status details message says that the "update applied successfully to the device."

Is there any way to clear this update from the Deploying and Available states?

Thank you for your help
