Wrong portfolio item url link redirection when WordPress SEO by Yoast plugin active

Hi,

Please can you help. On the test environment on: interpal.co on clicking on any portfolio gallery page it shows the link going to for example:
https://interpal.co/portfolio/hug-the-cactus

However on clicking on link it does to:
https://interpal.co/boldial/portfolio/uuuu-dr/

Please can you help me fix this problem, why does it go to the wrong link? I hope you can help and thank you in advance.

Kind Regards,
