Thank you for the appreciation, and I'm sorry you're disappointed, but yeah it's not supposed to be printed as a fillable pdf, it's supposed to be used online.
Maybe on the internet you can find some tool or addon that helps you do that from the Google Sheets file, or you can just create a fillable pdf using some tool (there are plenty).
If you prefer, though, I can refund you with no problem.
Let me know!
