Making copies of different sizes

Hello,

The question is the following, I deleted all duplicate photos that were created at different sizes and also cropped photos, which still will not be detected by this plugin.
But for some reason, after importing photos into the WordPress library, I again see the created thumbnails of different sizes.
Is this created by a plugin or theme? I didn’t find in the topic that it crops the photo.

I want to get rid of the extra amount of thumbnails of different sizes, but I’m running into creating them again because there are a lot of them being created.
