How do I change the Liberation Sans font which seems to be embedded in the fillable text boxes in a pdf I created?

I created a fillable pdf form using Libre Writer, utilizing Form Controls for the fillable text boxes. I am using Version 5.0.3.2. When I send the form to a recipient to fill it out, and they try to type within the fillable text boxes, all that shows is a line of dots. Sometimes, there is a message that says that the Liberation Sans font cannot be read (or words to that effect). I would like to somehow change the text boxes to accept a more common font, such as Arial, that most recipients would have in their devices.

you can do this via Toolbar Form Controls, Toggle Design Mode, Control Properties and select another font
