Folders, Appendices and ToC

At the end of my book, I have some appendices. I organise them in a folder called Appendices. When I compile my ebook, the folder appears in the table of content with a chapter tag and number. How can I get rid of the tag and still keep my folder/structure?

Thank you,

Go into the Title Adjustments compile option pane and locate the Do not add title prefix or suffix to documents option. Click on the gear button beside it and select any items that should not use the standard chapter <$n> prefix you’re using.
