Hook Issue since last Update

Hello, since the last update of GP Pro 1.11.1 the hook "generate_before_content" no longer works.

<p class="kategorie"><?php 
$categories = get_the_category();
if ( ! empty( $categories ) ) {
    echo esc_html( $categories[0]->name );   
}
?>
</p>

Display Rule: All archives

Issue: Output occurs only once above the first data record and not above each

I need Support, thanks!
