Monsterdex Bug

I like to keep track of my collections on games like this, and since collecting all mons will be a little hard, i have the goal of having all mons as “seen” on the monsterdex and was keeping track of which ones i was missing. Thing is, after the Island Challenge, i noticed that all the mons i picked on the draft for my team disappear from my monsterdex. The only excpetion were the mythics, and i already noticed that some of them had disappeared before, like the Deviladus line that i saw when i did the Rina’s story and the ultra challenge. Any way to fix this?

I’ve reported this one month ago. Devs would fix it in next update.
