Calendar sync problem for Samsung Galaxy Nexus

[linguistrick]

I have now used MyPhoneExplorer for more than two years. I had a problem once before with calendar sync for my specific phone (Samsung Galaxy Nexus) and you sent me to a page that had a special bug fix just for my phone. However, when I updated the program the bug fix didn't carry across, and I can't remember where the special page was! I have two problems: first, each time I sync it updates lots of calendar entries that I haven't made any change to, and second, even though the MyPhoneExplorer program shows that all of my calendar entries are on my phone, most of them are invisible on my phone, which is really frustrating!
