Remove Portfolio Title

After an update my Portfolio header reappeared on each of my portfolio pages.
How do I remove it?

Hey there,

I hope you are well today and thank you for your question.

You can try achieving this by adding the following CSS code in the Custom CSS option of your theme on the below path.

Admin Area -> Appearance -> Customize -> Additional CSS

/*remove portfolio title*/
.jetpack-portfolio-template-default {
    display: none !important;

Best Regards,
