Destructible Mesh not showing interior material

For any destructible mesh I create no internal material seems to appear. Is this a bug in 4.20? I tried with basic meshes so I’m sure it’s not the meshe’s problem.

When Destructed

Easy answer is:
Unreal abandoned Apex destruction and added these bugs to force us to switch to their Hard to use chaos destruction. It’s just like when apple slows down apps on old phones to push you to get newer phones.
