Ellipses appear strangely

Just installed 3.0 on my PC this morning. Smart quotes and em dashes are working fine, but ellipses are appearing as two dots and a space, not three dots. It’s not just an error in one instance; it’s throughout the document. If it’s how the ellipsis is supposed to look in the editor, that will end up being confusing. Every time I manually correct to three dots, it automatically changes to two dots and a space.

What gives?
