There seems to be a problem that the ZENKAI awakening panel of Super Saiyan Bardock is not displayed.It is also announced on official Twitter.
[Notice of defects]
Currently, it has been confirmed that the awakening core / awakening panel of "Super Saiyan Bardock" is not displayed even if it becomes ★ 7 or higher.When this phenomenon occurs, it will be displayed correctly by executing Title screen> Support> Clear temporary data.We apologize for any inconvenience.— Dragon Ball Legends Official (@db_legends_jp) October 7, 2020
Select Support by title for improvement
Clearing the temporary data seems to cure it.I thought it would be cured by logging in again, but it didn't improve, so I wrote an article.
It seems to clear the cache of temporary data, and save data is not deleted.
Check the ZENKAI awakening panel.
