Dear Elisa,
Thanks for your updates and reply.
The settings in the screenshot are in Word and I'm afraid that Excel may have no such settings as Excel's formatting is mainly related to the cell formatting. You may click on Format Cell to adjust the text font, the cell border, the text alignment and so on in Excel as what is showed in my screenshot above.
So could you find the settings in your screenshot in the Word application you are using? Is the issue in your environment that you can't find such settings in the Word application you are using?
If yes, please upload a full screenshot of the Account page in the Word application you are using for our reference. You can access the page via clicking on File>Account.
Note: Remove any private information before uploading the screenshots.
