cloaking issues

so I found this tutorial from Tesla Dev on youtube for cloaking:

and I got everything setup the way he did but my character model is has more materials then the default Unreal mannequin. so this is what my blueprint looks like:

but when I push F, to have him uncloak. only the arms/head comes back which is the first material

I’m using the Infiltrator Redshirt model from the Infiltrator learn project.
Anybody have an idea on how I can fix this so everything comes back?
