My assumption would be that gathering pure download data is easier than view data.
Since this is to do with how the site collects analytics,; I think you would get a better answer if you posted in "community->itch.io->questions and support"
I'd recommend adding your time zone and a link to the game (I have nothing to do with the site, but that makes sense to me).
Happy to hear you got 33 downloads in a day though. 4 downloads is a big day for me.
Best of luck.
