--- Comment #6 from Babak Razmjoo <b.razmjoo at protonmail.com> ---
Cathy, This is NOT a bug, nor an unexpected behaviour if you can understand
basics of Open Document Format (ODF) and the manner LibreOffice uses it to save
your documents.

A document saved in ODF is a set of XML files, possibly along with some
graphics stored in a directory hierarchy and zipped into a single file. If you
open an ODF (or ODT...) file with an archive manager, You can see them.

Using ZIP or any other compression format to compress some files means the list
modification in the source files (here XML) will cause a huge difference in the
resulting compressed file (see
https://computer.howstuffworks.com/file-compression.htm)

Hope this was useful
