Can't stop writer from adding numbers to RTF document paragraphs

Open RTF document then LO adds " 1. " in front of text which came from originally an odt document saved as RTF. There does not seem to be a way to stop this. I have tried everything I found on the web and in ChatGPT to no avail. The numbers are always added. There is no way to turn them off upon opening a RTF document. The only way to get rid of them is to edit the RTF document which is time-consuming and inefficient. This seems strange as other applications like macOS text edit does not add numbers. Is there a way to stop this behavior?
This is with the current version 25 as well as the previous version 24 on macOS.

Attach a sample RTF document with the problem. This looks like the application of a list style though there is no such possibility from RTF. So, need an example to analyse.

In the dialogue reached from the menu item Tools > Line Numbering, is the box Show numbering unticked?

Thanks for responding.

I think I see what’s going on. The headings for paragraphs were styled as heading 1 heading 2 etc… This choice of paragraph style also meant that an outline hierarchy was created as viewed in navigator. So what I had to do to eliminate the outline number pretended to the header text, was change the paragraph style as found under tools > heading numbering > headers paragraph style > none. Then these paragraph headers disappear from the navigator outline and the document can be saved as a RTF document without the pre-pended outline level to the header text.

It was tricky because viewing the RTF document in the macOS TextEdit program did not show the pre-pended outline level numbers, it swallowed them. But they were still there. If I opened one of these RTF documents in the macOS app Pages then these outline level numbers would again appear pre-pended to headers.

There was no “line numbering”.

MacOS TextEdit is a text editor (albeit quite enhanced and capable of reading more than simple text documents). It is not a “document processor” like Writer or Word. Consequently it ignores silently formatting directives.
