Problem with double gallery Photoswipe

Hello, I have wordpress version 4.4.3 with NOSH theme installed, I have a problem with integration of photoswipe, I followed the guide and documentation but it seems to be a problem, I have created a page with some gallery but when I click on an image it opens 2 galleries, the first one is the default of wordpress and when I close it I can see photoswipe gallery, I need only photoswipe gallery that I see in every demo, I put link “none” under the image so I don’t know how to solve this problem.
You can see the problem here:
