ZENworks Configuration Management 2017 Update 4
When Mobile Bundle assignments are made to users, desktop devices are shown in all (device, user, distribution, install, launch) of the Mobile Bundle dashlets.
This is fixed in version 2020 - see KB 7024113 "ZENworks Configuration Management 2020 - update information and list of fixes" which can be found at https://support.microfocus.com/kb/doc.php?id=7024113
Note: This issue will be fixed in ZENworks 2020 for new bundles. However existing bundles will still show the problem. Contact Micro Focus Customer Care, ZENworks support team for a script to run on agents to fix the problem for older bundles if needed.
