disable auto bookmark, chapter or segment

[mimdal]

I have an issue that I haven’t been able to resolve through searching—perhaps I’m not using the right keywords. When a video file has no bookmarks (or chapters or segments—I’m not sure what Jellyfin calls them), and the video starts, Jellyfin displays a message: "Fetching additional data." After a while, it loads bookmarks for every second, causing Jellyfin clients to slow down and stop functioning properly. I thought the plugin "Chapter Segments Provider" was the cause of the problem, so I uninstalled it, and I disabled Metadata downloaders (Episodes) option in admin panel, However this behavior persists. I attached a picture for two video files, one has the problem and another is OK.
