Buying Dragon Ball Sparking Zero in-game task

[Alexyumi]

Hello I am currently trying to get two titles in Dragon Ball Sparking Zero that require me to play ranked. Here are the following task:

-Achieve A1 in solo Ranked
-Achieve A1 in DP Ranked

Let me know if anyone can help. Already have the platinum for this game just trying to complete all the in-game challenges/titles.

Thanks.
