Kindle Jailbreak showing "Kindle Feedback" in home screen.

[aliasor]

I have already factory reset my Kindle because i read that you can't jailbreak without the "Kindle Feedback" showing but it is still there after. On my kindle there are no files exept the "fonts" folder (which is empty exept the standart "readme" file) and documents, where nothing is inside. I have show hidden files turned on and there is literally nothing else. How can i get rid of it? OCD kicking in and just want to have it removed.. Thanks alot in advance!
