Hi JGlennDM,
Welcome to the Community Forum. Sorry to hear you meet this problem, and I am glad to help you on this case.
Based on your description, you can’t add the footnote content at the end of the page while you have footer added on the page at the same time. I test that by my side and I have no issue to add both footer and footnote together on the same page. As you haven’t
mentioned whether you are using Word for Mac or Word for Windows, I just test in Word for Windows. See the screenshot below:

If the issue only happens to a specific document, please try to copy and paste content to a new created one to see the result.
If the issue happens to all documents even a new created one, to check whether the issue is related to the corrupt Word template, please first try to use another template to see the result.
To further help you, we need your help to provide us the information below:
1.
Are you using Word for mac or Word for Windows? Please provide us the screenshot of the Word version. If you are using Word for Windows, please go to File > Account > Product Information to get the screenshot. If you are using Word for
Mac, please go to Word > About Word to get the screenshot. To protect your privacy, please help to mask email address.
2.
Does the issue happen to only a specific document file or all files even a new created one?
3.
Please check whether my reproduce steps are the same as yours. Add the footer on the page then add a footnote. If that is convenient for you, I would like to collect a reproduce video from your side to know more clearly how the issue looks
like. To collect the video, I have sent a private message. Please access it via
this link.
Best Regards,
