Unluckily, it seems the Steem-based blogs doesn't show all the notifications (upvotes, mention, comments, and so on). It frequently happens to me also: I tried to review my settings on personal profile, but I didn't find anything to change for a better result. So... I only can suggest you to consult my blog once a week, if you want to check the Photochain challenge status or news (now, I publish the post between Sunday night and Monday morning, UTC+1 time zone), or you can consult the #photochain -marked posts.
