Found these warnings on the site health page

Hi,

The plugin is working very well on many websites we manage.
Today I found these two warnings on the info tab of the site health page:

Warning: Undefined property: stdClass::$stream_name in /home/user/www.domain.tld/current/wp-content/plugins/postmark-approved-wordpress-plugin/includes/class-postmark-debug.php on line 56

Warning: Undefined property: stdClass::$force_from in /home/user/www.domain.tld/current/wp-content/plugins/postmark-approved-wordpress-plugin/includes/class-postmark-debug.php on line 66
