Numerama.com text feed is sometimes garbage

Hello,

I’m reading Numerama.com feed.

When using the “text” feed view (that tries to extract text from the article itself, not the feed AFAIK) some articles contains garbage.
For example, Chiffrez vos messages et appels avec Signal sur Android contains more than 1000 repetitions of the URL as the article content.

Do you have any idea why? Thanks!

Feed URL is Numerama.

e.g. for that article above:
