Unwanted digits added to Heading 1, 2, or 3 of Writer document

Hi. I appreciate your help with this bug. After installing LibreOffice on Windows 7, I noticed after creating and saving a document, saved in RTF, that unwanted digits were added on all Heading lines. For example, it might look like this:

0 Chapter One
The Holy Scriptures

Where the Zero is unwanted and is uneditable.

How do I remedy this?

Go to Tools → Outline Numbering → Numbering tab and set Number field to None. Do this for individual levels or if you want to apply it to all at once, select 1-10 level from the box on the left.

Probably → Bug 49692 - RTF export/import: extra numbering for heading 1


Bugfix available in → LibreOffice 3.5.4


No reproducible with LIbreO 3.5.4.

Maybe uploading the file, could make easy for someone help.
