7 wild dates disappeared after 6th date

Does your sim have any trait that prevents them from getting stressed? The reward trait Carefree (purchased in the reward store) and some earned reward traits  (the one from completing the Island Living aspiration and I think one of the HSY teen aspirations also gives you something similar, not sure re any other aspirations). If so, that prevents the seventh moodlet from appearing as it's a stress moodlet vs a romantic moodlet.  Also, one of the positive Parenthood Character values will make the stress moodlet go away much more quickly, probably the one that helps with emotional control (my sim had all of them so I can't be sure which one it was) so when my sim got to the seventh date that stress moodlet went down much quicker than the timer indicated, but I rushed through and was able to get it done, but just barely.

Best regards,
