How to make text box background transparent

Hello LibreOffice.

I will like to take the opportunity to thank LibreOffice for making the software absolutely free. For people who can afford
expenses program like adobe…

I have a problem I am trying to figure out for two days, I am not sure if you can help me, if not. How can you point me to the right direction to get this done.

I am trying to create a fillable. When I modify it as a fillable PDF, it types but you is seeing the text box on the PDF file.

How can I fix this? or What can I do to work around this problem?

Please view the attached file

Thanks in advance

Cheers.
