It calculated it by itself, I think it made an incorrect estimate.
You payed about 730 satoshi / byte. So yeah... something got whacked.
The slidebar is supposed to pay between 4-100 satoshi / byte.
Could you go into the fee dialog and see what is checked?
I did notice that they changed the Fee dialog from 0.8.5 to 0.10.2
Then you have a volume bar. You can turn the fee volume down (3.89 satoshi/byte)
Or you turn the fee volume all the way up (122 satoshi/byte)
