Quixel bridge Problem with cache & Master material

I’ve been using ue5 and quixel bridge which works well, I decided to make changed to the master material to suite my needs that also worked as I intended it too.

I then moved onto a new project and tried to use quixel bridge only to quickly discover that the master material is an exact duplicate of previous project which means the material is references another file not necessarily unique to a specific project, that also means since I modified the material it could work in some projects and/or break in others depending on my needs.

tl;dl how do I get quixel to copy the master material rather than just referencing it?
