A puzzle started on wrong position

I had a very strange case on this puzzle this morning :https://www.chess.com/puzzles/problem/1781798

The starting position was wrong, this is the first time ever I encounter this issue.
Instead of having the bishop on h4, it was on g4.

But in this position a light square bishop makes little sense, so I examined the position for a long time (which is uncommon for a 700 rated problem for me) so I'm quite sure of the bishop initial position.
The only sensible moves were Bc8, Be2 and Kc3 which I did choose in a despair...

Later examining my 3 wrong solves in a new window I saw the bishop in h4 and was immediately extremely surprised.

I don't know how this is possible, but here it is !
Has anyone experienced something similar ?

I know I get this too clicking on the link, but while in puzzle rush this morning it was presented to me with the bishop on g4.

Yet since I'm not a streamer, I do not have a video proof for it
