OK, I got it reversed then. I knew it was one way or the other!

I can't see how the issue would be the OS version. However, I use pandoc 3.5 on ARM macOS (previous version), and I don't have any difficulties customizing the style....

Note that in my-reference-docx-3_5.docx, styles.xml has ``` ``` and the name specified here is "Title", not "Titel". So any localization of that name must be happening somewhere outside the stylesheet....

[EDITED] We produce a docx with ``` ``` and the way Word deals with this is to look up the style with `styleId` = `"Title"`. The default pandoc reference.docx has...

@ctfysh I don't understand the problem yet. See the last comment before yours. If you want to give precise instructions about how to reproduce this, I can try to reproduce...
