Particle Systems II - Not working in its default state

Hey everyone! 

I am a beginner but have previously worked with After Effects before. I've come across an issue recently that I have not been able to resolve (the support agent via remote screen aid wasn't able to resolve either), the issue is with CC Particle Systems II where upon dragging it + CC Composite onto a text, the particles do not seem to be functioning in a flow from left to right, but rather 'upwards' instead. 

I've attached a screenshot of a side-by-side tutorial I am following for a text sand effect. 

The left is the actual video I am following through up to around 4:14 on the timeframe. The right is my workflow space where I have replicated all the same options they have inputted into the effect, however the result is completely different where the particles are pointed upwards in a continuous cone rather than a 'scattering' flow like in the video.

This is not the first time I have followed this tutorial and achieved the effect a few years ago, but for some reason I am not able to. I'm using the old version of After Effects 22.0 (which I originally successfully replicated on), and have also tried this on 23.0+ / newer versions as well, all which led to the same failed result.

If anyone could possibly help advise me on this where I am going wrong or if it's an After Effects issue would be appreciated as I am going out of my mind!
