I can control more than 1 "Stellar Wind Wolfrayet"

Here’s what happened (note that this happened in local, not online):

I do some Ursarctic plays and end my turn on “Stellar Wind Wolfrayet”, “Ursarctic Mikbilis” and some other monsters with “Hop Ear Squadron” in hand. During my opponent’s turn, I activate Hop Ear target Mikbilis and summon a second Wolfrayet. Both stay on the field.

Can you provide a replay?

Most likely has to do with the synchro legality check of Hop Earred not confirming that Wolfrayet’s requirement of one being on field is met.
