Sims in Copperhead City have the wrong names
I just downloaded Copperhead City to add as a Downtown for Strangetown, but on plugging it into a test hood I found that multiple Sims in the hood have the wrong names. A guy whose bio calls him Danny Button is actually named Rebecca Patch, nobody in the Olsen house has the same surname (and first names are also obviously wrong: Rosario is named Justus, Bjorn is called Jacqueline), etc. I tried the main hood version and have the same problem there. Bios and LTWs appear to match up to context and are probably correct, but obviously I don't know the hood well enough to be sure if any other data is messed up.
HoodChecker hasn't been able to correct it. Is this a known issue? Is there an updated download out there somewhere, or something simple I can do on my end with SimPE? I don't mind renaming sims if that's the only issue, but I'm concerned this might point to a deeper problem.
