TESR down face not rendering

[Lyon]

Hello,

I created a block in which I want to render a smaller cube. As I want to resize the smaller cube I am using a TESR to render it.

The problem is, that the face at the bottom of the block is being rendered like the top face. So, if I look down on it it is visible, but when I look up to it it is invisible.

I really have no clue what the problem is, so every help is appreciated.
