Feed reader fires on old events?

Third party integrations
1

Been using IFTTT before to send me emails on updates on RSS feeds and realized I should be able to do this in HA instead. I added FeedReader integration with an RSS feed and then set this up:

alias: rss test
description: ""
triggers:
  - trigger: event
    event_type: feedreader
    event_data:
      feed_url: https://www.sweclockers.com/feeds/forum/trad/999559
conditions: []
actions:
  - action: notify.mail_me
    metadata: {}
    data:
      title: rss test
      target: [email protected]
      message: |-
        Url {{trigger.event.data.link}}
        title {{trigger.event.data.title}}
        desc {{trigger.event.data.description}}
        content {{trigger.event.data.content}}
        ---
        contents of {{ trigger }}
mode: single

Everytime there is a new post in this forum thread, I want to be notified. It kinda works except when there is a new post, I will get about one email an hour with the same rss event until there there is a new post, then that is spammed and so on.

Is there some setting I am missing?
