Wordfence finding issues after Downgrade/Upgrade

Hi there,

I used this plugin some weeks ago to downgrade my WP and I updated it again to the newest version after that.

Now Wordfence finds a lot of issues and after a google search I read that this may be due to a downgrade. I read that these issues may just be files that were installed at the downgrade. Unfortunately Wordfence keeps finding these issues and I wonder if I could just delete these files?

For exmaple these are:
Unknown file in WordPress core: wp-includes/sodium_compat/autoload-php7.php
Unknown file in WordPress core: wp-includes/rest-api/search/class-wp-rest-post-format-search-handler.php
Unknown file in WordPress core: wp-includes/js/jquery/ui/tooltip.js

Thanks!
