Axis experiments and Ball Drop issue

Art:
I decided to use Fusion 360 to create objects for use with Ticker.
I’m creating Ticker projects to understand/test several things:
Creating STLs from Fusion 360. (pretty straight forward)
Creation of Assets from STL’s
Differing apparent definitions of coordinate systems
Creating Switch and Ball-drop assets
Using Fusion 360, I created tapered cones (20mm base tapering to ~9mm with a 4mm hole). Three cones were created: Cone Base on XY plane with axis along +Z; Cone Base on XZ plane with axis along +Y axis; Cone Base on YZ plane with axis along +X axis. I exported these cones as STLs.
Using Ticker Asset Creation I imported the individual files. I got unexpected results for the Cone along the +Z-axis. The cone appeared upside down. I recreated the cone in Fusion 360 with the cone aligned with the -Z-axis. This one did appear as I expected.
During Asset Creation I shifted the cone X-axis and Y-axis to shift their bases to be at zero which then creates shafts that are half buried in the bases of the cones.
I used the same cones to create switches and also ball droppers to experiment with.
I created a project, AxisOrientationBallDropsV01, by importing the cones and also the ball dropper based cones. Each object was created with only Position Lock on. I arranged the cones near the top left to right X-axis, Y-axis, Z-axis. I arranged the ball dropper cones further down on the work area in the same right to left order.
For the ball droppers, I selected a rep rate of 2 seconds, 10mm Objects. Default objects on X-axis dropper, Spheres on Y-Axis dropper, Random objects on Z-axis.
The Experiment:
When I started the simulation I was surprised that all of the objects rotated toward me and placed their respective shafts to be parallel to the XY plane. I’m trying to understand why this happened. I could easily prevent this rotation by simply locking their orientation.
A separate oddity was with the ball croppers. The Y-axis dropper had Sphere selected but dropped cubes instead.
There is another variation of this experiment that discovered a possible bug...but more of that later if I create a simpler scenario to illustrate the problem.
Appreciate the time you are taking both in developing and debugging the Ticker program. Once I understand the program better
