pdf not attached to website but google

Life's Abundance Cat Food (premium-cat-products.com)

when i click on a pdf from this site - instead of showong the pdf attached to the website

it is attached to google

so if you click below 

https://premium-cat-products.com/breeder-program

and scroll to compensation plan which is a pdf - it opens but with GOOGLE

shouldn't it be the link below?

https://premium-cat-products.com/compensation-plan.pdf

thanks
