where do I change sender of ‘forgot password’ ?

Hi, I have a problem and the woocommerce support could not help me out. They have tried but they also say that this issue is not covered by their support.

So I hope I can get it fixed with your help <3

What’s the problem?

I use the ‘forgotten password’ on my website gripopeetgedrag.nl but when I test this I receive the (test)mail from the sender ‘leven zonder eetbuien’ instead of ‘grip op eetgedrag’. In the woocommerce settings – mails -the sender name is my name ‘Klaziena Waerts’, so even that doesn’t work.

I can’t find where to change the sender of the ‘forgot password’ mail.

I have tried already the plugin CB Change Mail Sender and the code

add_filter( ‘wp_mail_from_name’, ‘custom_wpse_mail_from_name’ );
function custom_wpse_mail_from_name( $original_email_from ) {
return ‘Yours Truly’;
}

which I’have found on https://wordpress.stackexchange.com/questions/173818/how-can-i-change-the-email-sender-name-from-wordpress-to-myblogname-on-the-lo

I also have disabled all the plugin for the conflict test but also then still the same issue ??

Who know what to do?

Thank you very much for your help in advance! ??
