DETAIL
I just checked your project, and I think you're referring to "8-BIT CLASSICAL MUSIC PACK – VOLUME 1 – FOR RETRO AND PIXELART GAMES."
If that's the case, it's actually set to "paid," and if someone wants to download it, they'll first have to purchase it for $7 USD.
The box with the value is not displayed because the game title is too long and the page simply hides it.
