Ah, I have no idea why it says that - it is set of 'physical game' and all the documents are either 'ebook' or 'documentation'. I don't use Steam at all!
I think this must have appeared when I was trying to figure out how external keys worked and if I could link my Itch to Max Moon's shop. I've managed to remove it now. Thanks for letting me know where the confusion had arisen!
