So, after hitting the forums I stumbled across the answer.
- Open the iSync application.
- Go to the preferences of iSync.
- Under the ‘Advanced’ section is a button that says ‘Reset sync history…’
- Press that button.
- It may be helpful to restart your computer.
And that should do it – it worked on mine at least.
(Next up a tip that will be handy for anyone who lives in a city with a public transport system)
