An Empty Box on the announcement

Description of issue or problem I’m having:
I am new to using OJS so this question may seem unimportant for most users. However, I am bothered by this. I created an announcement on our journal and I see an empty box on the right side of the announcement. I uploaded a screenshot of the box. What is the box for? If it has any use, how to use it?
The version of OJS we are using is Thank you.
