Easy when you know how. I now have it working how I want. Thank you for your time and guidance.
The Default Browser bar and New Folders had been deleted immediately after posting. The Spacer Bar as I now know its name had been moved but always sprung back.. I had not deleted it earlier as I was not sure of its purpose. I had already been in that area when replacing the missing icons.
The big clean up does not exist. What was not visible on the cut off screen grabs under Imported was a complete bookmark library type index that has been used over many years currently with 30 subject folders.
In each are at least multiples of two and three level sub folders selecting further detail paths for each subject. This has served me well providing a comprehensive system for several hundred bookmarks and thankfully imported well.
Best Regards
