[SyncEvolution] Nokia E72 calendar not syncing

Dear list members, (Please apologize if this is a double post, I'm having a hard time getting my messages to the list.) I am new to Syncevolution and I'm having trouble getting my calendar synced. I tried to follow Suyog's good tutorial there : http://mobileyog.blogspot.com/2010/06/easiest-way-to-sync-your-mobile-pho... My config (and phone) is exactly the same! (Ubuntu 10.04). But I can't sync my calendar events: there's just no checkbox for them. If I choose "Repair..." I do see check boxes (appointments / appointments and tasks) but they are both greyed out. This is for direct sync, but even stranger, all the network sync option also miss a checkbox for appointments. Contacts and notes, however, do sync well, but I really need to get my calendar events synced! Thanks in advance for any help - regards, -- Daniel CLEMENT
