SEO in wordpress [title tag problem]

Hello

I have a problem to print mi title tag i use:
<?php bloginfo(‘description’); ?> and i test also with <?php echo category_description(get_category_by_slug(‘category-slug’)->term_id); ?> in the header.php but if you visit the site https://www.venaixtapa.com/ven/index.php/playas/ the title is inside the <p> tag. How avoid this? i dont want to show the “p” tag in my categories titles.

Help Please ??
