7 Wild Dates ends after first 24h despite perfect date

How I understand it is that once you accept the challenge you get an extra flirty moodlet in which they also keep track on how many perfect dates you've had. You get 24 hours to have your first perfect date while you have that moodlet. If you've had a perfect date in those 24 hours the score in the moodlet says 1/7 perfect dates. After that you get a new extra flirty moodlet for another 24 hours so you can have a second perfect date. This goes on until you've finished the 7 dates. Although I've understood that for the last 24 hours you get a tense moodlet. But I've never gotten that far. 

What happens to me every time I accept this challenge, is that after the first 24 hours I don't get the extra flirty moodlet again and it says that I have failed the challenge. Even though it says in the moodlet that I've had 1/7 perfect dates and I've also had a pop up saying that the date was absolutely perfect and get a reward for it.
