Created attachment 148059 [details] screenshot 1. Open a Writer document in localized LibreOffice Online, e.g. in German version. 2. Open Format -> Bullets and Numbering from menu, and select the Customize tab. (In German: Format -> Aufzählungszeichen und Nummerierung, Anpassen) 3. The character styles dropdown is in English as it is shown on the screenshot. The relevant piece of code could be in here: https://opengrok.libreoffice.org/xref/core/sw/source/core/doc/DocumentStylePoolManager.cxx
Moving to NEW and turning it into an easyhack since there's a codepointer
this is a specific symptom of a broader problem: the localized built-in style names are stored in the model of all applications (at least sw and sc, pretty sure also sd), instead of the model storing only the en-US built-in style names and the UI creating the translations. there is bug 123397 for an ODF interop issue with the same cause; the solution proposed there doesn't look like an easy-hack.
Seems this is no longer relevant with JS dialog, translation is OK.
