I don't know why I haven't noticed this before, but it seems that there is something wrong with some of the German translations that are included in the SESB 3 (LU 84, EÜ 2, REB, GNB, ZB 2007).
A search for e.g. "Abel" in "Search All Bible Text" in "All Passages" shows double entries for every single result:

It should look like this (same search with ESV), of course:

Please notice that the total result number in the LU 84 (and EÜ 2, REB, GNB, ZB 2007) search is wrong, too - it says 44 when it should be 24, indeed.
Any idea what the problem might be?
