"only me section" of segment limited to 26 lines

Yes, I see the same limitation of 26 "only me" results, though unlike in your case, the list does not continue with "everyone" results. It simply ends at the 26th rank.

However, you can unlock the remaining entries by selecting your age category. The list then shows all your results (I have couple of hundreds of them on some segments), and they stay visible even if you then switch back to "all age groups". At least, it works with me.
