I am trying to do my regular DM sync and the sync wants to delete over 200 calendar entries on my desktop from within the past few months. I don't understand as all these entries are currently both on my device and my computer. I like to keep my old appointments and do not do this. The only way I can prevent this prompt is to do a one way sync from my device to my computer. I think things have changed since downloading 4.5 OS as there are several different calendars listed now on my device. It is trying to delete all appointments from a certain calendar but not the other one. I don't know why it seperates calendars as it is not necessary. Anyone following me here and can offer advice would be appreciated.
