Bored of every update duplicating contacts in Entourage

Question

Okay, I'm bored with the fact that every time I install an update to I-Tunes or the I-Phone every contact in Entourage is duplicated, including holidays. I now have each day of Ramadan and every other religious or secular holiday showing up 5-6 times on both my laptop and my phone, and regular appointments/events at least twice.
The only way I have found to address this is to individually delete the extra listings, and I am thoroughly tired of doing this, especially since it has to be done so often. There MUST be a better way!
Please advise.

Just have a look at the result and tell me how you THINK that it is correct!
