Apply scale and recalculate Normals

The selected object has a negative scale. Despite you see it light grey in the viewport, the faces are indeed flipped for the modifiers, as the object transformations are runned after them.

Notice that the same result can be achieved by simply give to the X scale a positive value, but to avoid misbehavior in future operations is better to fix the scale once for all:
