LEAP BRIDGE STEEL Wearing Surface Definition Error

When inputting a Wearing surface it appears Leap bridge steel incorrectly adds the load in the wrong direction as it is producing positive moments in a 3 span 64-80-64 over the bents. I ran the model with the definition of 2 in wearing surface and also adding 2 in to the slab. see moment results for Girder 2 below. 

Same model with 8 in slab and 2 in wearing surface

And wearing surface only

The wearing surface is producing a positive moment over piers.
