Question DrawMeshInstanced / ECS Based Animation not working on Game window

Hi Everyone.
I'm trying to do a little experiment on animations using Entity Component System.
I'm basically applying what's done here:

I'm using DrawMeshInstanced to draw layer batches, and each layer has a small Z difference.

The experiment has a top down view.

For instance, I have drawings that consist of 3 Layers:
Torso / Arms / Head , Head will have the greatest Z value, in order to appear on top of Arms and Torso. Torso has the least Z value, therefore it will be on bottom.

Since this has a Top down view, I'm calling DrawMeshInstanced on bottom sprites first, and top sprite last, that way they are rendered in the right order, one on top the other.

I'm seeing a weird issue where the drawings look good on the 'Scene' view but once I go to the 'Game' view, they're not entirely rendering (seems like some parts might be blocking the others, but I don't get why it only happens on Game view)

Here's an example:

Does anybody know what could be happening here?

Regards!
