Some of CCK's help topics can't be displayed by the Advanced help module

I already asked in the forum about this, but since nobody could give me an answer, I assumed this was a bug. Here is the original message:

I just installed cck and views, and I learned that a module called Advanced help existed. I enabled the module after I enabled cck and views, but although most of the advanced help looks OK, there seem to be some display problems with CCK 2's advanced help.

What I currently have under the advanced help menu is:

* Advanced help
* Content
* Node Reference
* Number
* Option Widgets
* Text
* User Reference
* Views

What is under the Content link is the majority of CCK's help supplement -- it works fine. But the Node Reference, Number, Option Widgets, Text and User Reference links -- which obviously should be a part of CCK's help too -- are broken, and give me warning messages like:

warning: uasort() [function.uasort]: The argument should be an array in sites\all\modules\advanced_help\advanced_help.module on line 241.
warning: Invalid argument supplied for foreach() in sites\all\modules\advanced_help\advanced_help.module on line 243.

Can I fix this? Do these help topics actually exist? Is this just a bug? Which module is actually responsible for the errors: CCK or Advanced help?
