Vespiquen (Paldea Evolved) forced me to shuffle a Combee under another Vespiquen into my deck

DefHalan

I used the "Order a Raid" attack using Vespiquen from Paldea Evolved, and I was forced to shuffle a Combee under a Vespiquen back into the deck, leaving the Vespiquen on the field. My next attack worked correctly as I didn't have any Combee under any other Vespiquen. That first situation was not how the attack should work
