This problem started when I upgraded from Ubuntu 19.10 to Ubuntu 20.04. LibreOffice is now Version: 126.96.36.199, Build ID: 1:6.4.2-0ubuntu3. When I do a Save As, the space for the document is not blank or the name of the existing file I want to overwrite, but the name at the top of the subdirectory I am saving into. This problem is unique to current version of LibreOffice. It does not occur with other software I use such as PDF Studio 2018 Pro.
How do I get LibreOffice to perform correctly? Current Save As is a major problem not only when I download documents from the Internet, BUT ALSO when I the Export directly as PDF function. LibreOffice now wants to put the wrong name on the new PDF file.
