Taxonomy Access Control: can still create node in other terms

Issue Summary

Hi,
The Taxonomy Access Control module seems the module I need. It appears however not to do what I expect it to do.

The following example shows what functionality I would like to have.

I have vocabulary “channels” with terms “politics1”, “politics2”, “economics1”, “economics2”, “sports1” and “sports2”. I have users Peter, Eric and Stan. Peter writes articles about politics, Eric about economics and Stan about sports. I want them to be able to submit articles in their own channels but not in the others. When Peter writes his article and submits it I want him to be able to select either channel politics1 or politics2. He should not be able to submit to the other channels.
I have created 3 roles: Politics, Economics and Sports. Peter is in role Politics, Eric in role Economics and Stan in role Sports.
I have installed the Taxonomy Access Control module and configured it for each role. For the role Politics I set the following:
- term politics1: View:A, Update:A, Delete:A, Create:checked, List:checked
- term politics2: View:A, Update:A, Delete:A, Create:checked, List:checked
- term economics1: View:D, Update:D, Delete:D, Create: not checked, List:not checked
- term economics2: View:D, Update:D, Delete:D, Create: not checked, List: not checked
- term sports1: View:D, Update:D, Delete:D, Create: not checked, List: not checked
- term sports2: View:D, Update:D, Delete:D, Create: not checked, List: not checked

When Peter submits an article he can select politics1 or politics 2 but also economics1, economics2, sports1 and sports2. So he can submit his article to each of the 6 channels. This is not what I want and not what I expected.

Am I doing something wrong? Am I misinterpreting what this module does? I played with it for almost a day now and can not figure out what goes wrong.

At the moment I use Drupal version 5.7, Taxonomy Access Module 5.x-1.x-dev (tried 5.x-1.1 as well). I use MySql

Any help is highly appreciated.
