Unwanted Loads/Moments showing up with Load Case Manager results

I am using Load Case Manager to setup and run 11 primary load cases and 17 combination load cases. I am using a User-Defined coordinate system rather than the Global CS, and I have carefully selected my moments and forces in accordance with my User-defined CS. When I view the results table under the Results View tab, I am getting an additional load with the opposite sign populating an unmarked column adjacent to the non-suppressed load in the table. See images below of Load case table setup for Normal Force (NF) and the NF Results View. Attached setup file in .csv format below, and you will see that it also includes the (-100 N-m Moment about the x-axis), but there should not even be any value in that cell given the below definition.

- I only want a NF of -100 lbf along the z-axis, but LCM automatically added a -100 lbf-in moment about the x-axis for some reason. This has been occurring consistently (with different unwanted loads/moments showing up each time) and it is messing up my results as you will see in the Results View image below.

It seems like a bug in the software since since the Moment radio button isn't even checked in the Definition, but it keeps messing up my results each time I attempt to run the Load Case Manager. I have already tried closing/reopening the LCM and I have even deleted and rebuilt the LCM cases 3+ times to see if the software was holding onto some settings somewhere.

Anyone have experience with this issue or will I need to address it directly with SW?
