Weird Effect

Hello All,

Im pretty handy with WordPress but this has me baffled. I’m hoping you can help. Usually, my titles look normal and below above my content (https://ontheflipsidecomics.com/strange-worlds/page-28/). I must have triggered something because now I get the title above my content and it seems to be inside this grey box along with the name of the author of the post (https://ontheflipsidecomics.com/young-love/page-43). What the heck did I do and how do I correct this? All my other posts look normal. hoping you can help. Thank you!!!
