Xgen issues - reapplying to character after mixamo

[Anonymous]

originaloriginal rendermixamonew project, mixamo importnew renderHi 
Im pretty new to all this and am close to pulling my hair out.
I have built, textured and applied xgen to a character in maya, exported as an obj then taken it into mixamo, to get some simple animations for a presentation. I download the animations and import them to a new project in maya. 
I have then reapplied materials to my character and this is where my issues begin. I want to now add the xgen description i made in my original project to the same character in the new project. but I'm loosing all the grooming, tweaking and shader that I previously added in the original. I've tried exporting the xgen collection then re-importing and this is what I get. I've also tried to export grooming and I get the same result. 
HELP

Thanks everyone..
