If any of these are intentional, then that’s totally cool, just think at least some of them are probably remnants that have gone unnoticed.
Also, just as general feedback, I think the reply counters for the

Never displaying reply counters of 0 might also be a good policy overall, although I’m not sure how granular the controls are in Discourse.
