Hi there, @Christy24K.

Thanks for taking the time to follow along with the thread and sharing your concerns. I'm happy to further explain how to close the books and provide some screenshots. 

To edit the settings, you'll need to click on the pencil icon on the right-hand side of the screen. You can reference my screenshot below. 

After you select the pencil icon, you'll need to click on the slide bar next to Close the Books. 

Once you've clicked on the slide bar to turn on the Close the Books feature, you can enter a date. 

However, if you still do not see the option, I recommend Clearing the Cache from your browser. Web browsers collect cache to save time when loading repetitive data and images. Over time these files can become outdated and corrupted, causing issues like the one with your missing box.

Please let me know if you have any additional questions or concerns. I'm always around to lend a hand. Take care!
