Lost all BAT collected in the past 2 weeks

Hi there, I have updated the latest version of brave this morning.

And after that my BAT collected in the past 2 weeks are all gone.

(I am a new user since early April so I am pretty sure the BAT hasn’t been transferred to Uphold wallet.)

Also it’s not counting any new Ad I have received.

Is this a bug of the latest version of Brave?
