Thanks for the heads' up! I've seen this with a couple previous chapter updates and I think it has something to do with all of Itch's servers not updating at the same time. I'm 90% sure this will correct itself if you check back on it later/tomorrow but I'll go through some of my old comments and see if there's anything I can do to speed that up. :)
Sorry, I didn't see the reply on this! The downloads appear to be kosher across the board- I haven't had other hiccups or troubles with them from others at this stage. The dates are REALLY off and don't match up with what I'm seeing both logged in as a publisher and logged off /looking at the public page. I'm going to submit a ticket to itch since I don't appear to have direct control over the display here. If I get anything salient back, I'll let you know!
