If you have a lot of access levels and sub access levels you might need to increase the default setting that controls this in ApplicationSettings.properties settings:

 # If a user's browser does not support JavaScript then checkboxes are used for specifying categories (on search, add asset etc). These become unmanageable when there are too many categories, so when that is the case just the top-level categories will be shown. This is the max number of categories before that happens.
maxNumCatsForNonJS=500

 If there are more access levels than this amount then Asset Bank will only show the top level ones.
