I just noticed that the first resource added states Category under Information rather than "Author." LPH is the author of the resource and not a category.
Well, I went to the phrase and it had been changed. This may have been from changes made last year for the Library add-on. Reverted phrase and it now says "author" as it should.
FWIW, the "Authors" phrase states XenForo Resource Manager in description. Author does not.
