problems with trusting in key --recipient or --default-recipient

Hallo!

For my first question the answer was really easy, but the second one seems
to be more difficult.

perhaps someone knows why the following problem occours, if I
choose --recipient instead of --default-recipient(which I´ve never chosen
somewhere, I have just tried out:-)) With --default-recipient everything
works without any problem, but is it correct? Because there will be a reason
for the following dialog in the commadnd-line, if I just take --recipient:
