Your menu, dear user, might be generated incorrectly because of various reasons.
I would suggest checking if the ../pages/this.kstr file is written with correct syntax and all the files and folders listed do exist. Items listed as URLs need to have a this.kstr inside, where only one line should be written and that's the target url. Check if all your listed folders have a declaration as 'ß' keyword.
Non-existent items are automatically skipped by generating script which might cause your menu to be generated wrong. Commenting lines with '//' at the beginning of the line that you have prepared for future use is recommended.
Also - don't forget to clear the cache, otherwise the script won't generate the new menu (If you're unsure about the changes, save the last generated file before doing so).
