It all comes down to permission. If you get the map that Gam posted, then your issue for the checkboxes is a permissions one.
C:\Users\SERVER\AppData\Roaming\7DaysToDie\Saves
...in your dedi save folder there's a file called webpermission.xml
That's where you set up "permission levels" to allow users access, based on their steam accounts in serveradmin.xml
Hope that makes sense.
Setting permission level to 2000 will allow everyone to access the list item.
