Designer not letting me view and edit hero image until i hit preview, then exit preview. After going in preview Designer lets me edit my hero image. Why? Is this a glitch?

When you go to my homepage read link, you will see the hero image doesn’t appear unless you hit preview first. Then if you exit the preview everything works fine and the homepage image appears and I can edit it in Designer… Why? It loads like this sometimes. How can i fix this? Is this a glitch?(will attach photos here) Thank you so much!
