You can easily clear entire views of your calendar schedule with the Clear Schedule feature.
Go to the tab ShiftPlanning and click on the downward arrow icon beside Publish button. Select Clear Schedule option there.
First, make sure you are in the 'View' that shows the shifts that you want to delete. Please note that if you are in the 'Day' view it will delete all the shifts in that day.
If you are in the 'Week' view it will delete all shifts in that week.
Lastly, if you are in the 4 Weeks view it will delete all shifts created for those 4 weeks which are being displayed.
