Filtering in ZuluCalendarList not working

[icastro]

Hello, 

 

I have published calendars on iCal based on two separate tables. One of them, a "projects" table, is working fine, but the calendars for the second table ("tasks") are not showing up correctly.  
The calendars are publishing and I can see them but they appear blank. The calendar content is filtered using the zulu_FilterKey, and I filtered through the staff field, and the zulu_FilterValue is the staff member's name. Hence only tasks for that specific person will show. 

Any ideas on how to get the filtering back up?

 

Thanks in advance, 

Iris
