Boolean Union is differencing instead

I have two meshes that I am trying to boolean together and the boolean either fails or it instead acts as a MeshBooleanDifference and cuts away at one of my forms.

I’m not sure why the boolean is failing in the first place, usually if I just shift things a little a failed boolean will “magically” work but that hasn’t been working for this either.

I have attached the file I’m working on
BooleanTest.3dm (830.5 KB)

Hello- please see

Anything there helpful?
