Seo title redirect to another page

Hello

I’m facing an issue in a specific product page. https://www.marseem.com/doll/phillip/

Once I click on it the link redirect me to another title (https://www.marseem.com/doll/handmade-dolls/

Once I deactivate seo plugin the problem disappears. But why like this? all product pages work perfectly except the mentioned one. I tried to delete all seo in this product page but no luck.

Any recommendation?

The page I need help with: [log in to see the link]
