Mobile robots.txt error after update to J!5

Hi all

After upgrading to J!5 from J!4, in Google`s PageSpeed Insights, I got the SEO error "robots.txt is not valid 69 errors found" for mobile. I'm not sure if this is something controlled by the Gridbox component. Any ideas towards pointing out a solution are very much welcomed.

Domain is localelift.com

Kind regards
