A bug? Filter removes feeds that shouldn't be removed?

Hello, what am I missing? RSSGuard does receive news from from this feed with the filter enabled, but seemingly many items get filtered out that shouldn't be. Interestingly enough I noticed this by enabling notifications and seeing the deleted articles in the notification box.

The feed
https://www.real.discount/rss

Feed item example
https://www.real.discount/offer/essential-after-effects-from-beginner-to-motion-master-36861 Tue, 28 May 2024 13:01:01 GMT https://www.real.discount/offer/essential-after-effects-from-beginner-to-motion-master-36861 ]]> Published: 2024-02-23 12:16:07, Duration: 3.0 hours, Design Eye-Catching Motion Graphics with After Effects Even as a Beginner

The filter:

var blacklist = [
'Python',
'Excel',
'Exams',
'Practice Tests',
'SQL',
'Cómo',
'Drupal',
'Introducción',
'Apprendre',
'Agile',
'HTML5',
'Experto',
'Angular',
'C++',
'Diploma',
'PHP',
'10Web',
'iOS',
'PowerPoint',
'Hindi',
'सी',
'खें'
];

function filterMessage() {
  if (blacklist.some(i => msg.title.indexOf(i) != -1)) {
    return MessageObject.Ignore;
  } else {
    return MessageObject.Accept;
  }
}

Yeah something sketchy is going on here. It might not even be the filter, but RSSguard just skips some of the articles from that feed, although showing them in the notification balloon.
