BBC and BBC(fast) recipes are not working

Hello.
these 2 recipes , BBC and BBC(fast), are not working.

They retrieve no articles from the feeds, for example https://feeds.bbci.co.uk/news/politics/rss.xml.

It seems the recipe only keeps the article containing the term '>window.__INITIAL_DATA__="{' .

Only a few articles have these words. All other articles are rejected.

But I am not enough expert to solve this issue

I thank you for your help
