I think you have misundertood the BookMark Object.
BookMark Object shows all the available User BookMarks.
Now it will display the name only when you select that BookMark.
So in your case, you have selected the Historical_Ravi, so the book mark shows that name, but as you also have the CUrrent_Satish, so this names are shown in dropdown list.
I hope you understood this
