Hi, you asked me to explain the problems with the Bookmarks that cant be imported correctly. When they are imported they are all contained inside a folder as shown in this photo.
It's the Yellow folder on the top left here that says "20161029 From HTML"
The Bookmarks used to appear like this photo below when I imported them or signed in to the browser and Synced the Bookmarks. They were all in a row and not inside a folder :
And on the far right side of that row of Bookmarks was an arrow you could click on which opened all of the bookmarks .... shown just above the Red arrow in this picture :
