Fezandipiti ex drew 2 cards instead of 3 during flip the script

Is Flip the script bugged?

After my opponent phantom dived my active charmeleon and benched hootoot on turn 3 of my ranked game, I drew Nest Ball and played it to get Fezandipiti ex from my deck on my next turn. I activated Flip the Script and instead of drawing 3=three cards, I only drew two. The Battle Log showed that I drew three (Fan Rotom, Buddy Buddy Poffin, and Area Zero Underdepths), but only the Fan Rotom and Buddy Buddy Poffin were visible while I drew and in my hand after flip the script activated (Which was upsetting because I needed the Area Zero Underdepths to expand my board).

Is this a known issue?
