Why doesn't my template want to work?

Question

1C-Bitrix

The guys ran into a problem that I have never encountered before.
I add the Bitrix:news Component to the page. I copy the template to my templates
. I set up bitrix news.list.
I'm trying to set up bitrix news.detail - nothing changes.
It turned out that bitrix.news.detail is pulled from the
/bitrix/components/bitrix/news/templates/.default/bitrix/news.detail/.default folder
And, no matter what I do, it is still pulled from there.
I already threw Bitrix.news into my namespace - nothing.
I created a separate template for bitrix news detail, but Bitrix doesn't even respond to the detail.php file
I don't know what to do!
