I've seen the issue, and fixed it and uploaed a fix for it a few days ago - I'm not sure but maybe itch.io caches old files or something.. could you try a new download and see if it's fixed for you? I've noticed you're not the only one who's seen this bug either. Thanks for playing and letting me know.
edit: I see the issue too, ye it's after you play the game once - I'll patch it in the next release, thanks again.
