Problem in collection redirection

Developer help
1

I have following routes.yml file.

routes:
  /learn/: 
    data: 
      post: page.home
    template: page

collections:
  /hls-streaming/:
    permalink: /hls-streaming/{slug}/
    template: index
    filter: primary_tag:hls-streaming

  /learn/:
    permalink: /learn/{slug}/
    template: index
    filter: primary_tag:-hls-streaming

  

taxonomies:
  tag: /learn/tag/{slug}/
  author: /learn/author/{slug}/

When I am trying to access https://example.com/hls-streaming/adaptive-bitrate-streaming/ it always redirects to https://example.com/learn/adaptive-bitrate-streaming/

I have added correct pirmary tag to that post but I am not sure why it ends up redirecting.
