Sometimes, the computer messes up in your favor.

I am not sure what to make of this, since aa.com says first class gives you 50% bonus miles (or is that international first only, while domestic gets 25%)? Either way, it seems that the computer messed up, because I should only get 100% based on PLT status and no COS (neither 25 nor 50).
