Configuration of BC for Boston to Munich flight

Hello fellow travelers,
Twice now, I see a change in the BC A380 configuration for my flight in Iuly.
When I booked, it was 2-2-2. It changed to 1-2-1 a while ago. And now it’s back to 2-2-2.
What gives?
I understand that this can change at the very last minute, but why it is flipping 40 odds days ahead of time?
Thank you in advance.
