After downgrading from 5.5 to 5.4.2, Wordfence found unknown files from WP core

Hi,

I used your plugin to downgrade WP from 5.5 to 5.4.2.

Now Wordfence tells me that I have a lot of unknown files in WP core folders (wp-admin and wp-includes).

Could you please confirm these files are WP 5.5 core files that the plugin left untouched there, and what your plugin did was just copy to wp-admin and wp-include folders the core files of the WP version to which I wanted to downgrade, in my case the 5.4.2 version?

Many thanks

List of file names in wp-admin and wp-includes after downgrading, which are considered unknown by Wordfence:
