Hello,
Images 2 and 3 are not related with K2. They are from a different component.
As for the buttons, there is a css conflict. There is nothing broken, it is a visual issue. I have to disagree with your template's developer.
Either way double check the: media/k2/assets/css/k2.frontend.css file so that it is the same as the default one.
