IdStory Identity Manager

Bug encountered in release 9.0.0 .

I created new user "fiserp", user has superAdminRole. Then I did some testing and wanted to delete my user afterwards.
I logged under "admin" user, checked "fiserp" in the list of users and tried to remove it.
IdM displays a yellow popup that "Example module is disabled". (Example module is disabled - it was never enabled in the first place.)
Upon clicking execute to proceed with deletion, the popup appears over and over.
User cannot be deleted.

Accompanying stacktrace:

eu.bcvsolutions.idm.core.security.api.exception.ModuleDisabledException: Module [example] is disabled.
