breadcrumb never disappear completely

Dear,
why the last part of the breadcrumb of my resource never disappear? (screenshot)
Also if I did this in my resources

public static function getBreadcrumb(): string
    {
        return '';
    }

public static function getBreadcrumb(): string
    {
        return '';
    }

Solution

I think you would need to do something like:

public function getBreadcrumbs(): array
{
    return [];
}

public function getBreadcrumbs(): array
{
    return [];
}

for each of the pages like

ListXXX.php

ListXXX.php

CreateXXX.php

CreateXXX.php

EditPHP.php

EditPHP.php

etc. do disable the breadcrumbs
