Importing to Unity causes messed up animations

[1kirigiri]

When I imported my sprites using Spriter2Unity, the animations look very off when played.

I see two issues here that may or may not be related to each other:

1. The Game preview has the sprites in odd z-order.

2. The dress of the character is moving unusually. In Spriter, the animation looks just fine.

I am very confused as to why this is happening. 

Note: I am aware of the issue of "Pivot points that are assigned on the canvas. Right now if you do this, your sprite will be misaligned when imported in Unity." However, I changed all the default pivot points on the file palette.
