How to change the Drupalexp template for portfolios

I purchased this template, I noticed there are various nice templates for portfolios, but I am not able to change the default template used to another one. Plus I was also unable to remove the display of certain fields such as project url, client etc.

Hi guys,

All is block, views,.. so you can hover to it and click to configurate button and hidden it.

And if you want remove a field of a content type. you can manage field of conten type in admin panel and delete it.
