Screenshot of the problem
The LibreOffice is configured for English (US) UI, and Russian (default) locale.
When I apply a cardinal (and ordinal) numbering to a text which is English, the preview is still in Locale language (Russian). (Ordinal lists have problems with Russian - see bug 117584). I suppose that current text language should be used instead.
Tested with: Version: 18.104.22.168.alpha1+ (x64)
Build ID: 23c5125148a8110d88385b29570bf0b7d4400458
CPU threads: 12; OS: Windows 10.0; UI render: default;
Locale: ru-RU (ru_RU); Calc: CL
I reproduce the problem with LO 22.214.171.124.beta2+ configured with the UI in English and a text in English. As my locale is French (fr_FR) I see the preview in French instead of the language of my text (English).
Set status to NEW.
Best regards. JBF
