Basically, when working with LibreOffice you should always save in ODF format. In Draw this is ODG. If necessary, you can then create a copy in another file format.
However, it is not certain that the result looks like the ODF format.
Information can be found here in the FAQ.
Unfortunately, you do not describe your preferences in detail, which leads to the result shown. Man (me) can not understand it that way.
Since I have just created a similar example for a video, I attach it here. Maybe it will help you.

You can then upload the file here. To do this, edit your initial question. Don’t answer if it is not a solution to your initial question. Edit your question or write a comment. And let me know which operating system you are using. Thank you very much.
