On Speedfit Design Simulator, both warnings occur at the same time. How can it be solved?

Hi everyone,

I have a question about the loss simulator (Speedfit). When i start to simulate CAB450M12XM3 SiC module according to the parameters below, i'm getting a warning that is showned in the picture below with green highlighted. This is about the load inductance. In the picture above at the schematic view side simulator says L must be higher than 0,01mH. At the bottom side simulator says L must be below 0,01. So, it can not be run to extract the power loss solutions. i appreciate anyone who helps me to solve this. Take care.
