Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
You can use the snippet editor within the Rank Math metabox to add the meta title manually. It allows you to manually edit the meta values as well.

Looking forward to helping you.

How do I delete these titles?

Hello,
Those fields need to have a value so if you empty them, Rank Math will eventually add the default value. It cannot be empty.
If you wish to remove the title tag from a certain post type, you may need to apply this filter code:
add_filter( 'rank_math/frontend/title', function( $title ) {
$post_type = get_post_type(get_queried_object());
if ($post_type == 'your post type'){
unset($title);
}
return $title;
});
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
OK everything is fine, thanks bro

Hi bro
How do I delete the description?
I adding code like this, right?
https://ibb.co/1KJ8BKF
Hello,
Please replace the line where you are unsettling the description with something like this:
$description = '';
Don’t hesitate to get in touch if you have any other questions.
Where should I insert it?
<?php
add_filter( ‘rank_math/frontend/title’, function( $title ) {
$post_type = get_post_type(get_queried_object());
if ($post_type == ‘wp-manga’){
unset($title);
}
return $title;
});
$description = ”;
Is this correct?
Hello,
If you want to completely remove the meta description, the filter should look like this:
add_filter( 'rank_math/frontend/description', function( $description ) {
$description = '';
return $description;
});
From your screenshot, you can remove this line: unset($description);
Then replace it with this: $description = '';
I hope that helps.
Thank you.
