A few weeks back I re-imported meta data trying to find a product, and since then several of the items in my smart content library are duplicates. Is there a process to remove duplicate thumbs or do I have to delete them manually? And if I delete them manually will it delete the product associated with it?

Also, I have a number of product thumbs in black and white that are asking me to install them, but they've already been installed through DIM, I just can't access them until I install them from the library. Why is this?

I'd ask this on the daz forums but they seem to be down for maintenance at the moment.
