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?
