An unassigned driver is on the "driver 1 strategy" instead of one of my actual drivers.
My drivers #1 and #2 are assigned to both my cars and they were the ones to qualify. But I can only set the strategy for one of them.
I even fired the unassigned driver to see if it would fix it, but no, he's still there. So I might be racing with only one car?
Also, the chat doesn't seem to be working. I tried to share this problem there and it's just not showing up.
it also happened to me in the past. the cause could be that you changed your driver 1 or 2 during this week, it's a bug. the driver that you can't see on the strategy page will race with a default strategy that could be very bad.
next week it will be ok, in case you need to add a new driver 1 or 2 do it after the race and before the monday update.
