I have the same problem. I use OF on my Mac and iPhone. I've used the OF sync server, but because of the duplication of repeating tasks I swithced to Bonjour - maybe it will help me, what do You think?
Maybe the app should force sync after we check off repeating task (not every task, only the repeating one - because it cause the duplication problem) ?
I hope You will find a way to fix this problem, because it waste of time: deleting duplicates tasks and thinking: "did I check off this task?"
