Hey Snoop, finally got a reply from itch support, they replied with this
Hello,
Unfortunately, because the developer is using per file pricing, it overrides bundle and sale pricing. Your purchase was for $9.00, and the developer is requiring a purchase of $17.99 or more to access the full content. They will need to remove that requirement if they desire for people who paid less to have access. Please let us know if there is anything else we can assist you with.
Thank you
