Lake trio quest help

[Satwe]

Hello,

 

I dont know if this is wrong topic to post here but i need some help for this quest

 

Probably i had started this quest a while ago and after quitting for a few years i came back and tried to continue. I see that i have seen data of palkia, arceus and dialga and also the lake trio i have been to all 3 lakes and have seen data of azel, uxie and mesprit. 

 

Although i meet all the requirements and fought with statues and lake trio When i speak to Dawn at the lab she tells me that i have not enough experience in Sinnoh and to come back later... I went also to the screen in my house and it says that so far no one has found the shiny stones but i went to all possible locations and there are no stones.. And also how could i skip the stones when i had fought with the statues anyway?

 

I dont know what i am missing, please help
