Precisions about titanic leap

Hi everyone,

I recenctly started to play Krosmaster Arena, and i need some help about a spell. 
Jahash's titanic leap is a 4-4 range spell, it means it can only be casted on the fourth cell away from him. However, on the rulebook, it's written "the targeted cell must be [...] 1 to 4 cells away". What is the rule concerning the spell?

Thank you!
