I hope you are well today and thank you for your question.
We can change developing CSS code.
Could you please share me the page URL from your site where it is displaying so that i can help you to change it?
I seem to have the same issue. I am using Portfolio because on Portfolio 2 you are not able to remove the link to page. It only removes the link icon, when you click on the image you still go to the portfolio page.
When i use regular Portfolio the remove link to page button does work. But in this portfolio it is not possible to change the color of the filters, also active and hover. I have tryed this using yellowpencil but was not succesful.
