Ah yes, I didn't notice the attribute samplers in the editor screenshot.
What seems to be the issue in Unity? Can you not change those samplers' positions?
You might need to update to the latest version of the plugin (2.9p3) as we fixed several bugs affecting the sampler attributes since 2.9. However please note that doing so would require an editor update as well (to v1.11) and re-baking the effects.
