Issues with the backpack traveler theme

I bought the backpack traveler theme and I’m trying to install the widgets, but it doesnt work at all, I can not change anything on the blog. for example I tried to put the backpack traveler instagram widget and it appears throughout the website, the images are giant and divided into two or three parts, and i dont know how to handle it. Could you help me?
