The Jobs created in Salesforce should be marked with "Ongoing" and "Display on Website", the Job and related Shifts are shown in the Web page/Calendar and in the V4S Kiosk application.
If you want a particular Job and related Shifts to be shown only on the V4S Kiosk application, mark the Job as "Ongoing" and "Display on Kiosk" in Salesforce. Then add the API name of the field "Display on Kiosk" in the V4S Mobile configuration screen in the "Filters for Jobs and Shifts". More information here for marking the changes in the V4S Kiosk filters related to Display on Kiosk filters
Now the Jobs and related Shifts for the Job which are marked as "Display on Kiosk" are shown only on the Kiosk application and not on the Web pages.
