Hello I want to change the content and there is not way to change it, and only edit with yellowpencil. Please let me know what to do and I have attached the backend code for it.
I hope you are well today and thank you for your question.
It seems you have created the content using the WPbakery page builder so, please make sure you have enabled the WPbakery page builder for the portfolios as shown in the attached screenshot.
