Thank you for your answer,again.
Finally, I found how to fix them. The featured photos should be set the width = 696px(before the width were set at 600px). Now it works perfectly in block 13.

* I did install plugin again. The site looked too ugly for me. I give up with block 13.

T_T I don’t know what I did wrong.
I uninstalled jetpack and svg icon plugins and the page looks very messy now.

Page name was on the right.
The featured photo is not displayed fully.

Thank you again for your support.
I tried to disable your suggested plugins(jetpack/svg icon) however, it could not fix and another topic also had the same problem. The excerpts also got shorter.
