I may have figured out what is going on here, the issue might be the sliders on the left, specifically the "Projected Range" slider. To show you what happens, go ahead and adjust a player and put him at 100 fantasy points. On the slider on the left you will see that the range adjusts to allow up to 100 Projected points to be filtered, however, the current position is still maintained so the player who is at 100 projection will be filtered out. What makes this a little more confusing, the filter does not apply immediately (so you can still see the player at 100 for now), this is by design, but it will apply once you adjust anything. You can make it apply by doing a sort, changing to a different pool, or adjusting any slider value. Also, if you refresh the page, the sliders initiate with the highest and lowest projections in your player pool, so it would show all of your players.

So, if you change a players projection outside of the range that was loaded when the page initialized, then you will run into this behavior.

Let me know if this is what is happening, I helped someone out via email with a similar issue.
