Pads Professional Library Question

I've finally got the hang of working with the Libraries for the most part, but I'm hung up on how to get rid of my duplicates. When I created this test Library, I somehow incorporated this Board1 into the mix and would like to get rid of it as I've set up separate partitions for the parts.

When I try to delete  say AZX0402 from Board1 iit won't let me.

If I drill down and prepare to delete the individual associated parts first - it allows this, but deletes them from every partition. 

The parts are redundant and also reside in the CAP partition.

Anyone know how to easily remove just the Board1 Partition while leaving the others unaffected?

Thanks,
