Issues with Libreoffice

I am encountering an issue while creating a PDF form in LibreOffice. In edit mode as ODT, the radio buttons and checkboxes are visible and functional. However, after exporting the document as a PDF, these elements do not respond. I am using Linux Mint with LibreOffice version 7.3.7.2 and have enabled dark mode on my system. How can I rectify this problem? Additionally, I would like to know how to switch specific software, like LibreOffice, to light mode while keeping the rest of my system in dark mode.Thanks and hopefully somebody will provide me resolutions.
