Player Development Problem

[mirko21]

halo i edit player on fifa 14 with cm14 and every player i edit won't develop
for example
i change ronaldo day of birth to 1994 and his potential to 99 and when i play
in career mode he won't develop even after 2 seasons

 

[The Crew]

his growth shouldn't rise in the first two years

but players that i won't edit develop even before the window transfers in the first season
