As you can see I just set the module like it should , in a propper module position, not embed in article with loadmodule.
although it could work with loadposition.
Your template doesn't seem to support the full width feature. This is the only issue I see with it.
Although I could address it for you adding a setting in the module.
As you can see at other sites in the demo, it usually works paerfectly and this is the most powerfull parallax module ou there
mix of full width, rotation, translations and scales

Full width , multiple instances on same page, scaling etc..

I propose you hold your breath a little more so I can add another fullwidth parameter to support t3 templates.
