Sometimes when I try to change the format of a paragraph by selecting the whole paragraph (manually) then changing something like boldness or character size (via hotkey or UI buttons), all text in the entire document is changed (eg, bolded) instead.
This behaviour persists even after closing all LibreOffice documents (I checked task manager and no LibreOffice processes remained) then reopening the offending document.
Is there something I could be doing wrong here, or is this definitely a bug?
