1. If I correctly understand your question, to set a custom project info heading text, go to :
Vision Portfolio->.. Edit your desired portfolio item, then scroll down to the bottom of the page and insert your custom text in “Project Info Heading” text field located in “Portfolio” tab in “Agama Options” meta box. https://prnt.sc/kt23he
2. To remove the “Skills” from the single portfolio item, remove all the skills from the “Skills” box on the right side.
To remove Client, empty “Project URL” and “Project URL Text” text fields located in “Portfolio” tab in “Agama Options” meta box.
