I've just migrated to Opera from Chrome, and I have a very large folder (900+ items). However, when I imported it into Opera, all the icons disappeared, and now display a file-like icon. What do I do? Is there any way to get the icons back other than opening all the tabs?
Thank you.

@xorinet To clarify: The folder I have is a bookmark folder.
