Simulation Units Confusion

I'm using SW 2019 Premium, the specified units are lbf.in. Does this translate to inch-pounds of torque? Based on my simulation results, the units are not correct. So my real question is what units are Simulation using?

 

For example, I have a machined screw (304SS) that I know from real testing, will fail at 80 ft-lbs of torque. Simulation says it will fail at 10 ft-lbs of torque if the units of lbf.in are truly the same as in-lbs.

The last image shows half of the torque that it takes to
