[itsm] Page for Freetext-fields gone

Hi, after installing the ITSM-packages on v2.2.2, there is an additional page "additional itsm-fields" (zusätzliche ITSM-Felder), but my page for the standard "freetext-fields" is no longer available. If I want to call the page via url, I get this error: Module Kernel::Modules::AgentTicketFreeText not registered in Kernel/Config.pm because Frontend::Module###AgentTicketFreeText and Ticket::Frontend::MenuModule###310-FreeText was disable automatically during ITSM-installation. Why? Perhaps to disable any backdoor for modifying the special freetext/time-fields which are used by ITSM? I enabled both and now the FreeText-page is available again. Is there any problem with this? Bye, Alex
