need help with comps.xml and anaconda installer

[devel anaconda <anaconda-devel yandex ru>]

Good day to everyone!

I have a little problem with trying to rebuild my own distro, based on RHEL5 SRPMS.

All srpms rebuilded sucessfuly, distro created sucessfuly, but I want to change some defaults with packages selection menu. 

I want the following:
If I choose in my distro "customize packages now", I wish, that every checkbox will be turned off, exept "Base" and "Core", but I can't get it :( In comps.xml, in <group> tag I found:
<id>editors</id>, then I found <default>true</default> and changed that to <default>false</default> but nothing happend :( After rebuild iso process, "Editors" checkbox still "On". Same problem with "Dialup", "Text based internet" and so on...

Please, can anybody halp me with some advise? Where am I wrong? Thank you very much!
