How did you transfer the other bookmarks?

Did you use a HTML or JSON backup or copied the file places.sqlite?

Here's what I do when transferring from one profile to another, on the same computer.

Go to "organize bookmarks", click on "bookmark toolbar", click on any bookmark in that category, click on menu "organize", click "select all", click on "organize" again, click "copy".

Then close firefox, start it again with the other profile, go to "organize bookmarks", click on "bookmark toolbar", click "organize", click "paste".

Now if you are moving to another computer, try save the copied content to a text file and move that text file to the other computer, then use "paste" inside firefox.

Good luck.
