Using channel entries twice

Hi, my problem is a very easy use case and so I’m not sure where the problem is

I have an url /members-news/catgroup/url-title

My code is looking like this

{!-- Section with the single news --}
{exp:channel:entries channel="news" url_title="{segment_3}"}
{title}
{/exp:channel:entries}

{!-- 2nd Section with a list of teaser news  --}
{exp:channel:entries channel="news" category_group="10" limit="4"}
{title}

{/exp:channel:entries}

In my 2nd section I always get only the news from the first section nothing else. The news is in this category group. And I want to use entry_id=”not …” But this is “future drama” 😊 since this simple request doesn’t work.

Can anybody help me??! Thanks a lot.
