I am trying to sync my database across multiple platforms (PC, 2 iPads, iPhone).  I have tried to use both to the PC database via wi-fi and to my online database - the issue is that each one shows a different number of entries in the database:

PC = 1279
iphone = 1269
ipad 1 = 1276
ipad 2 = 1273

shouldn't they all be the same?
