It has to do with the tabs, methinks. It selects the tab object and has you fill out the "content" field of that object, rather than letting you directly edit that section (I think...) Which makes it really hard to edit, since the entire page's contents are dumped in a tiny (~2 line) section lol.

Best bet is to just use the classic editor. Destiny's suggestion would work. You could also just click the arrow next to the edit button to open up a drop-down list, then select "Classic Editor" for one that will work with our tabs.
