Hmm, really wierd, as if Club is spawning, it has to be somewhere in the files, and I highly doubt you can move it from another .img-file to another by mistake.

Try searching for clover.txd, the club.dff/.txd should be right below it. I guess it could be a mal-function in the tools search-component.
And, I'd recommend to use IMG Manager v1.5, reliable and fast.
