FF usually can't recognize anything if its not the day or past the day.
For example, if i were to say i Ov.ed tomorrow, instead of today, FF wouldn't bother with it and send me a message like "you cant ov. in the future" or something like that. I would guess since you can put ahead temps in (and i knw you dont get messages for that)- its why you dont have the cross hairs. So once tomorrow comes around, it will recognize tomorrows temps. When the next day starts, it will recognize those temps, but it cant right now bc its in the future
