How to correct Heading Numbering Fonts Formatting errors?

LibreOffice 24.2.7 on Ubuntu 24.04
I do not use a snap version of LibreOffice.
In a 300 page document edited since some 3 years, I encounter the following
Heading Numbering Fonts Formatting Error:
Numbering font size is different from Heading font size
Additionally, in the “Set Paragraph Style” selection box, I lost the selection options
Heading 2
Heading 3
I have made a 1 page ODT document showing the inconsistent Heading font sizes at levels 2 and 3. I could upload this file. But I still do not see a way to upload this 1 page file in this ask.libreoffice forum.
