How to remove numbers in custom stencil pass?

In view port shows custom stencil pass with numbers, but when I render it to exr files, numbers are still there.
How to remove or disable this numbers while in render exr mode?

I want to know too D:

left is before, right is after.
Just remove where it layers the numbers on top in the CustomStencil in Engine Content
You can get rid of the lerp as well along with the brighten (or plug the same input into both A and B)

Turns out the same solution is suggested here: Custom Stencil pass, numbers - Cinematics & Media - Unreal Engine Forums

However his screenshot is rather confusing and almost looks as if he hasn’t changed anything. I ended up solving it myself and then noticing thats what his screenshot was supposed to show.
