Is there a way to sort the style-name list that appears pressing F11?

I use LibreOffice writer 4.2.3.3 installed in Debian wheezy.
I created many styles, but pressing F11 I get a non ordered name list. If I try to move one of them (to sort alphabetically), it will be included “inside” another, as based on the other, so no more independent.
How can I do to freely move an item of the name list?

At the top of the Style panel there is a choice of ways to display the styles Paragraph, Character, Frame, Page and List. At the bottom a choice of which Styles and how to show each group of files. There are a number of options including Hierarchical, All, Custom and Applied. The lists are alphabetical.

In the Hierarchical option If you move a Style so that it is included (Linked) to another in error, you can remove this link by Right Clicking the entry, select MODIFY and change the Linked With entry on the Style Panel / Organiser sub-panel and select -None- in that field. Hope this helps Peter

Thank you.
