Look at the local settings within the files and look at the global settings.
Also study the code to determine if the direction in correct after posting to compare what is correct vs the incorrect.
Outside of that having verification software would check the actual posted G-Code.
I looked at the files quickly and found something that could be causing the issue.
See this video.

One other thing to watch on Haas machines is there is a setting to "mirror" the axis, not sure why you would want to mirror an axis (just program it correctly).
Honestly neither (Unless you have licensed the Machsim module and have a Kinematic aware post) ....G-Code simulation or verification is the most accurate.
I have had it with the tools set to be numbered sequentially (for a Haas umbrella tool changer) and the tool number goes to say T1 and the H and D go to 0. Once I go into edit tool and type 1 into the T number it changes the D and H accordingly. But without doing this manually it sometimes puts in other numbers.
Not sure of the culprit.
This is what I experienced.......randomly changing although my control definition was set correctly. This was happening back in X7 and I have experienced it in MC2019, MC2020.
Best to look at one of the existing Machines to see how everything is saved. The folder name is important and the XML file name is as well, I think they need to match.
Everything looks correct except the Lead In/ Out Arc Entry and Exit. Then they get you to change the rough stepover to 20%. Then do the rolldie operation.
The tool just looks like it is cutting in the wrong location but after the verify finishes it looks correct.
+1 to using a ball nose end mill.
Also you can try using "Angle Increment" in Tool Axis control to make the vectors closer together (using a small number like 0.5 degrees or smaller)
I would suggest either contacting your reseller and or posting this question on the main Mastercam forum.

The reduced end does not look round so you are most likely going to have to make this in one setup as there is no way to locate the part.
We use 5C collets to hold parts like this using a fixture like these (to hold small round stock).

When in edit mode click on the axis in the tree and edit the direction (X,Y, Z) to get the direction you need.
If you need to change the pivot point change the Rot. Base Point.
