Why Slice9 doesn't work correctly for me?

[Hip]

I set the value to 90, then I tried to stretch the box with texture… But
the corners of Slice9 are stretched too. It’s strange,
What I doing wrong?

You do not stretch it, just change the width, height

Okay… Then what do I need to do to stretch it without corners?

You need to change the size, not scale.
