Wiley Publishing duplicating feed stories (dueling URLs)

I subscribe to a few scientific journal feeds from Wiley (such as Angewandte Chemie, ChemBioChem, etc. They apparently send out the same articles twice, with URLs that start with “https://www.onlinelibrary.wiley.com/” and again with “https://pericles.pericles-prod.literatumonline.com/” with the DOI appended to each.

Is there a way that I can tell Newsblur to completely ignore (say) the pericles URLs? I’ve been messing around with the training algorithm, but I don’t think it recognizes this sort of thing. Thanks! I’ve contacted Wiley themselves, and have a “We’re working on it”, but this has been a problem of theirs for a long time.
