Topic on Project:Support desk

i activate numbering of paragraphs in my user preferences. Then when displaying the page itself numbering is:

Sommaire
1 2 Welcome to MediaWiki.org help pages
2.1Reading
2.2Editing
2.3Advanced editing
2.4Collaboration
2.5Personal customization
2.6Wiki administration

Strange: There is nothing between level 1 and level 2 on first line and all is under level 2.

Then making modify source + preview with a forced TOC, all is under level 1:

Sommaire
1Welcome to MediaWiki.org help pages
1.1Reading
1.2Editing
1.3Advanced editing
1.4Collaboration
1.5Personal customization
1.6Wiki administration

Can someone analyse and correct the display ? Thanks. --Christian 🇫🇷 FR (talk) 09:04, 18 May 2024 (UTC)

What "page itself"? Please provide clear and full steps to reproduce something somewhere, including URLs.

it is written in the title, read the complete topic please. --Christian 🇫🇷 FR (talk) 08:39, 20 May 2024 (UTC)

This might have something to do with the change of the heading structure that is rolling out. Although I have proper spacing between the numbers and the titles. I suggest we wait a week or so more, before fixing this to allow changes to settle down.

thanks sometimes things appear strange to me, so I just warn. --Christian 🇫🇷 FR (talk) 10:18, 21 May 2024 (UTC)

In a similar way on page -> Help:Extension:Translate/Group_configuration/MediaWiki the numbering shows :

   1 2 Configuration file

There is only a single level == so there is no need to see a 2 and the two numbers are on the same item. With a forced TOC the structure is correct :

Sommaire
   1 Configuration file

More awful -> Manual_talk:LocalisationCache.php the numbering of the topics is doubled at each step :

1 2 role of this page ? 
3 4 ? as mentioned above

As a conclusion, with tag TOC numbering is ok, and with tag NOTOC and user-preferences requesting the numbering of headers, two numbers appear in front of each header.
