Unable to make PRESET for JPEG + RAW.

Hello, 

This is a serious issue and I'm pretty frustrated. I have downloaded Presets from creators using the DNG copy method and it copies fine to both JPEG + RAW photos. I can create a preset from that DNG and it looks the same on both RAW + JPEG. However, I am UNABLE to replicate this. I have tried creating a preset on a JPEG and when I copy those settings to a RAW image, nothing matches. I'm using Lightroom CC + Mobile. I would prefer not to use Lightroom Classic. 

My ultimate goal is to be able to make my own presets but if I can't make any that are compatible with RAW + JPEG, there's no use for me. 

I will edit on a JPEG However, If I copy these settings onto my RAW image, it does not even look close to the same? WHAT IS GOING ON?
