Superscore Calculation is using my Friends high score rather than mine

[Nod Nolan]

At the end of the game when the Score screen / table is up I am noticing that my superscore is using my friends high score for calulation not mine.

So for example on the GotG table, I scored a pitiful 3,117,478 on the table

but the superscore calculation is using Budlights 13,187,371 to make up the superscore.

Same problem here. All my friends with the game are experiencing it. Broadly speaking, the entire score/superscore/leaderboards thing seems completely borked.
