Need help bottom aligning text in a PDF fillable form

I have a form edited by multiple people. By default, the text in the form fields is bottom-aligned, but when some users edit the form, it appears as middle-aligned. When the text is middle-aligned, the user has made changes to it outside of Adobe, such as their browser, but after saving and sending the form, the text will default to middle-aligned even when edited in Adobe. How can I change the alignment to a form's fillable text?

Here is an example: On the left is after the user made changes online, and the right field is the original formatting.
