I also have had this problem until I noticed that the app synk's from all addresses listed to pull the info from.
So say you have your email address, an Amazon log in, or any other account addresses for the app to pull the info from, it will pull multiple times.
To fix this problem, go into the pull down and disable down to one account address.
Just your Amazon account name, or, l have found that just your email address.
Hope you understand and try this simple fix.
