For some reason, you chose to call function `bookmark-load'.
If you do that it behooves you to check its doc first ;-):

| bookmark-load is an interactive autoloaded Lisp function in
| `bookmark.el'.
| It is bound to <menu-bar> <edit> <bookmark> <load>.
| (bookmark-load FILE &optional OVERWRITE NO-MSG)
| Load bookmarks from FILE (which must be in bookmark format).
| Appends loaded bookmarks to the front of the list of bookmarks.  If
| optional second argument OVERWRITE is non-nil, existing bookmarks are
| destroyed.  Optional third arg NO-MSG means don't display any messages
| while loading.
| If you load a file that doesn't contain a proper bookmark alist, you
| will corrupt Emacs's bookmark list.  Generally, you should only load
| in files that were created with the bookmark functions in the first
| place.  Your own personal bookmark file, `~/.emacs.bmk', is
| maintained automatically by Emacs; you shouldn't need to load it
| explicitly.
| If you load a file containing bookmarks with the same names as
| bookmarks already present in your Emacs, the new bookmarks will get
| unique numeric suffixes "<2>", "<3>", etc.

See the last paragraph.  You are loading your bookmark file more
than once.  Most likely you are doing an explicit `bookmark-load'
when your bookmark file has already been loaded.  Don't do that. ;-)

You can use function `bookmark-maybe-load-default-file'
instead of `bookmark-load'.  (There is also variable
`bookmarks-already-loaded', but you should not need to check it.)

But before bothering to fiddle with such things, check what you
are really doing, to see how/why/where else you are loading your
bookmark file, and perhaps simplify your code accordingly.
