IMDB plugin cannot filter as expected

Here is my config:

pter_movie:
  rss:
    url: https://pterclub.com/torrentrss.php?rows=10&cat401=1&sou1=1&sou3=1&sou6=1&linktype=dl&passkey=xxx

    other_fields:
      - link
  no_entries_ok: yes
  quality:
    - 1080p
    - 2160p
  imdb_lookup: yes
  require_field: imdb_id
  imdb:
    min_score: 6.0
    min_votes: 100
  nexusphp:
    cookie: 'PHPSESSID=xxx; c_secure_uid=xxx'

    - movie_list: pter
  run_task:
    when: accepted
    task: send_to_radarr
  template:
    - qbittorrent_base_template
    - qbittorrent_add_movie_template

send_to_radarr:
  movie_list: pter
  accept_all: yes
  list_add:
    - radarr_list:

The nexusphp plug-in will grab the promotional information of the seeds,github:https://github.com/Juszoe/flexget-nexusphp. In my configuration, the nexusphp plug-in will accept free seeds. The function of qbittorrent_base_template and qbittorrent_add_movie_template is to send torrents to qb to download through the qbtorrent_mod plug-in,github:https://github.com/IvonWei/flexget_qbittorrent_mod.
In my expectation, flexget will only download free torrents with an imdb score greater than 6, and add the accepted movies to radarr. However, the imdb plugin does not seem to work, and some movies with an imdb rating below 6 have also been accepted. I checked the debug but still cannot find out the reason. Can anyone help me? Here is the debug log file https://cowtransfer.com/s/77a33c28e70d4c with the access code fgtt2u.

Help me, plz! QAQ
