Those all look right to me. I am thinking there must be something that went wrong with the other commands in between. I use the same primers and the silva database and haven’t had the same issue. The only thing I can recommend is to start from the beginning and go slow, checking each step and summary closely. Or maybe you can get Pat Schloss or Sarah Westcott’s attention and they can take a further look.
I found that this question has been addressed before here but it looks like the person who posted it found their mistake and got it to work.
