Why aren't all of my bookmarks from the stock browser from my Note 3 on my Note 4?

[AC Question]

I switched from an iPhone 4s to the Note 3 a long time ago and was able to use something to transfer all of my bookmarks to the Note 3. Now from the Note 3 to the Note 4 I've tried using the Samsung account. I've synced them on both devices and only about a quarter of the bookmarks have shown up on the Note 4. I am currently using the stock web browser.
