Single Hilti Bolt in Base Plate

We are trying to design a base plate with HIT-TY-200 V3 + HAS-V-36 anchor. Since this is for a small stair, we prefer to a single anchor. The loads are N= +/- 1 kip, Vy=0.5 kips, and Vx=0.75 kips. But HILTI PROFIS Suite does not go forward after the loads are input. Instead, a warning message is shown: Single anchor construction cannot be used with torsion. However, as you can see, no torsion is applied. Can you please show me how to design a single anchor base plate?
for the connection.
