Trouble with fillable text box size in Writer exported to PDF

I have created a fillable PDF form in Writer and when I export it as a PDF the large text box I have created which is meant to be several lines long will only let me fill in one line at the center of the box. Does anyone have any suggestions?
I am using Windows 11 Home and LibreOffice 7.2.5.2 (x64).
Thank you!
