You've got your line labeled incorrectly. Remember that the INLET side of the reducer always appears on the LEFT of the labe. In your thumbnail, it's got 10 first and then 8. It means you need to erase the reducer, set the line start size to 8, then reinsert the reducer and set the downstream size to 10.
