Hi,
Thanks for reporting this issue. There was a bug in our system when importing the articles.
We usually first try to import the article from the RSS Feed if the <content:encoded> field is available, and fallback to scraping only if the full content of the article is not available in the RSS Feed. But the content:encoded field is available in your feed, so the problem is on our side.
It has been fixed now, and we force-ran the cron jobs to re-import your articles with the fixed text, and cleared cache.
