You got it:

11. Bd8  [481 SOLUTIONS]
11. Bxd8 [1 SOLUTION]

Maybe it would help if you wouldn't try to make the problem harder by
leaving it open whether some white moves are captures or not. With "x"
instead of ":" the problem works: [1 SOLUTION].

I'm sorry if I got your intent wrong. I know that colon is the German
notation for capture, but the piece letters were not in German and you
used "x" in another problem. I really have little patience with non-strict
SAN. Sorry!
