Datacron not updated in squad arena

It seems, that an equipped datacron gets not updated in arena. I equipped a lvl 2 datacron did a fight. Afterwards i upgraded the datacron to lvl 3 but it already shows a lvl 2 in arena overview. Even after I did a fight with the lvl 3 datacron it only shows lvl 2 in arena overview.

Edit:
After I switched to another DC the overview shows the new one. Why I have to switch the datacron to get upgraded stats active? That's not uxp friendly.
