Blank Datacron Bonus on Reroll

Ummmm...yeah...that's not good. I'm playing on the PC client.

This is a fully upgraded (L9) cron rerolling the L3 bonus. It was my third total reroll on the cron. And, no, this isn't a scroll / text position issue. It really is blank.

Choosing the middle bonus gets me...

So it seems to be "just" a visual bug, since I actually did receive a rerolled bonus.
