Puzzle Lab bug. Unable to complete

The Boomsday Project Puzzle Lab is bugged. in the Secret Lab fight against Blast Dr. Doom, Puzzle 3/4, (the Northshire Cleric one), there is a bug where when doing the solution, after playing the card “The Swap”, two cards inexplicably die (one Cleric on either side of the board) and there isn’t enough damage on the board to finish the puzzle.

I have the same problem. Please fix

Follow this guide : https://www.hearthstonetopdecks.com/guides/lethal-puzzle-lab-solutions-guide/
But only for the first 7 steps
8. Play Treachery on your Silvanas
9. Use The Swap
10. Play Circle of Healing

You can work around the bug using the bug, Silvanas gets destroyed instead of swaping and steals the cleric you receive

Last puzzle doesn’t have the bug since you don’t swap a full board
