Unable to reset Material Instance values for blended materials

Hi, I was foolin around with blended materials. I blended 2 materials together just for fun, created a material instance, then changed some values for various parameters. All worked well until I tried to reset those values using the little yellow arrow buttons next to each parameter.

Apparently, I’m unable to reset parameter values back to their defaults for blended materials. Would be handy to be able to do so!

I’m using UE v4.7 Preview (Not Unreal Tournament)

Thanks!
