Issues achieving double sided foliage - UE 4.23

[JengaLenga]

I am attempting to make double sided foliage by masking out cut out planes with the Shading Model "Two Sided Foliage", but the issue I'm facing is that the backfaces are not visible at all UNLESS I check "Two Sided", but with "Two Sided" checked there are extreme issues with lighting/shading. I'm completely stumped and don't know how to fix this issue.

I have two photos attached to portray my issue.

I fixed it, here is the solution, you have to enable this in your material instance. As it is disabled by default for some reason in 4.23 and does not work unless you enable the override.
