Both pairs of radio buttons seem to be linked as one group of inputs. Whenever I click one of the four buttons, the dot moves to it. Even between the two separate pairs. And you'll notice that the first pair doesn't have a button to themselves.
Once I click an option, the page refreshes saying that the change has been updated however the radio defaults back to 'Feed'.
You may also notice that the 'Display Mode' section doesn't have a left margin.
Upon changing the Display Mode to List, the pages refresh but nothing seems to have changed.
The posts only display in list mode after you scroll down and reach the bottom of the page which then prompts it to load more.
Code block here!
