On the right side of the window, there are tabs for "Recent", "New", and "Popular". It appears that for an OP with no replied, in the "Recent" tab, it will show that the OP is a Reply. The "New" tab shows that the OP was a Post.
Thanks for posting Lynn! There will be cases where there is duplication, but I think those are functioning correctly since: Recent = Recent posts New = New topics We may swap those out with other lists, but for now we're testing those settings. We can also put in "most viewed" "most replied" and a slew of other options.
