Outlook Holidays show up in CRM as TODOs

We are using the Sync to Outlook tool for our Sage CRM.

Outlook has a feature, to insert all Holidays automatically. But if we do so, they all show up in the SageCRM under the category "Zu Bearbeiten". Is there a way to make SageCRM ignore these Holidays or chage the category to "In Bearbeitung"?

Thanks a lot for any help or input on this matter.
