File Integrity

When doing the “File Integrity checks” I get the following message “It appears as if some files may have been modified.
One possible reason for this may be that your installation contains translated versions. An easy way to clear this is to reinstall WordPress. Don’t worry. This will only affect WordPress’ own files, not your themes, plugins or uploaded media.” for all the default WordPress files.

Using Version 1.7.0 of the plugin.

Running version?6.4.3 of WordPress.

It is happening on all my sites.

Might be a different issue but php is getting the following error message “Undefined array key ‘status’ in wp-admin\includes\class-wp-site-health.php on line 3296” and “Undefined array key ‘status’ in wp-admin\includes\class-wp-site-health.php on line 3294”
