I found the solution to the problem on Microsoft's page and I hope that this page comes up for as many people as possible.
Select the text you want to stick to the bottom (or top) of the page. Under Layout tab take a look at the bottom right of the page layout section and you should see a small arrow that, when clicked on, opens a new menu. In that menu, go to layout tab and set vertical alignment to be "bottom". IMPORTANT! Make sue that the next menu option (at the bottom of that window) is set to "apply to selected sections" otherwise, you will be writing from the bottom of the page upwards.
Here is the source image that helped me. https://filestore.community.support.microsoft.com/api/images/0382c4a8-ade9-4fc4-be66-bcd2c7101479?upload=true
Here is the visual representation:

Note that the person who took the screenshot set the last setting to whole document, not just selected sections.
If selected sections option isn't available, make sure you selected a text before opening the menu.
Hope this helps!
