Missing column load in RC Pier WS auto generation

It appears that when the elevation at the top of the pier is negative ( for instance, the top of deck is set at 0.00), the software would generate the WS load on column or stem  (UDL ) for the STR III - 60 degree case only . 

No UDL on columns/ stems is generated for the other angles or load combinations.

This does not happen when the top of the pier has a positive elevation (e.g. the top of deck is set at +100.00).

Is this a know issue?

Can you please look into this?

Thanks.
