Layered Materials Not saving

So I create a layered material with 5 layers, connected to 5 material functions. However after I set it up I just could not save it, see error below. its under the instructions set limit, and as you can see the warning are not that bad. So any idea what I should do to save it?

In UE3 that error means you have that saved in the wrong location probably means the same thing in UE4 but I am not sure. Where are you saving your material to?

So where should I be saving them, I mean the material Functions save just fine with no issues.

Ok figured it out, the reason that I had this error was because I decided to copy and paste comments from 1 material to another
