I am playing in a 4th year of my junior player and he played some pro tournaments, with ranking between the 300 best players. Despite this, he can't enter in challenger tournaments, showing a message he don't have ranking high enough to qualify, but giving others optionals tournaments in that week, sometimes in best tournaments than that he would plan to play. I enter in a tournament this form, but I can't play a planned tournament.
I think this can be a bug.
