I copied it to Junior and it gives the following diagram

r4k2/p4ppp/3P3q/4P2P/3b1P2/1r6/pPQ3B1/K1B2R2 b - - 0 1

You can see that the first line is different

You wrote 4rk1 and fritz translated it to 4rk2

I guess that the right position is 14k1 that means this.

[D]1r4k1/p4ppp/3P3q/4P2P/3b1P2/1r6/pPQ3B1/K1B2R2 b - - 0 1

I also think that saying that Rebel is not better in tactics because of the fact
that it cannot find it is wrong because the difference between Qe6 and Bxb2+ is
only a positional difference.

I read that the main difference between the new Rebel and the old Rebel is
tactics.

I think that you should try more positions before deciding that Rebel is not
better in tactics.
