Replying to My threads "Mine" tab issue

When I try to go to page 2 or further back on the "Mine" tab in My Threads, it just links my to the "New" tab page 2 or 3. Is this because I may have cleared out all my threads with the death "unwatch all threads" button a couple years ago or is this happening to everyone? I know I have post dating back many years, but I could only go back 2 years in that tab.
