Error when making setup for theme path settings

Item 1
When adding 2 new paths in the setup:

admin/appearance/settings
admin/appearance/settings/*

an error appears after hitting the submit button:

Notice: Undefined index: remove in config_perms_admin_form_submit() (regel 173 van /home/domain/public_html/drupal-7/sites/all/modules/config_perms/config_perms.admin.inc).

Item 2
Viewing the page admin/appearance/settings unexpected theme names appear on top: dissabled theme's and also hidden themes. After unselecting the setup in item 1 this page shows the correct themes again.
