Can't submit Wanted Monsters?

Hello! Trying to find out if anyone else has this problem... I currently have 5 Frizzies, but when I try to turn them in to the Wanted Monsters activity, it shows I have 0/5 Frizzies. Am I doing something wrong? Thanks in advance!

EDIT: I suppose I should specify that, as of this post, there are still 6 hours and 37 minutes left for this activity, so I don't believe it's a deadline problem.

Did you get the frizzles before the event starts?

I think only monsters collected after the event started count. Once you got enough, the reward will automatically show up in your reward center.

I did have one of them as a lizzy before the event started, which I evolved into frizzy before getting four more lizzies (after the event started) and evolving them into frizzies. I wonder if that's why? Perhaps I had to capture them as their evolved form for it to count?

As it was, it never showed up as me having captured any before the event ended. Every time I checked, the page said 0/5, and my Reward Center didn't have anything, either

I'm sorry to inform you that only those obtained through synthesis, seal card capture, and egg-cracking are counted. Also, it is restricted to the event availability period only.
