Are you sure that you are not looking at the 1st, 2nd, 3rd, 4th page of a specific gallery?
Many people have their default landing page set as the gallery view, so if you click on a specific gallery icon, ... arrive at the images in that gallery, ... click on the pages of that gallery, then it is still the gallery view, but it is whatever page you click on of that gallery view.
Obviously, I am not experiencing this issue, ... to answer your question.
