Token summoned in the same monster zone as a set monster

Hi,

I had 1 monster (unchained twin - sarama) and 1 trap set, on my next turn, i use fiendsmith sanct to summon a token, and i seems to have missplaced my token as it was placed in the same zone occupied by my set monster.

On my screen, the monster i had set was showed in defense face up, with the stats of the token. when i was trying to summon fiendsmith requiem of the token (the summon was shown as aviable in the ED), i couldn’t select the token.

I could flip summon Sarama and use both monsters to summon unchained soul of yama but i had to “select” two times the same monster zone.
When i flipped summon sarama, it was briefly in attack position with the correct stats and switched in defense position with the token stats

I don’t have any replay that reproduce this behavior unfortunately, the replay show the token summoned next to the monster i had set
