Why did FF put those DUMB crosshairs back on my chart today????? I am SO CONFUSED!

They took them away yesterday and put them back today with the same possible O date.
The OPK that I did yesterday afternoon was the closest I have ever seen to positive. It was BY NO MEANS positive.....but all the other ones I have ever taken have had like NO second line.....and yesterday's had a second line that you could see from across the room!!

So, I had renewed spirit that maybe I am actually getting close to O'ing......THEN dumb FF put my crosshairs back today! And I really, really don't understand what I entered that made them do that?? Can someone explain it to me, please???
