Black Pixels in Stencil PNG turn Red in selection tool

[Val P]

Hello, I've encountered a problem. When I use an image as a stencil for Pose tool, all black pixels on it turn 100% red in selection and therefore the extrusion in mesh doesn't look correctly

 

Here's an alpha I'm using but the same issue is present in other similar alphas that have black pixels:

Try as 24 bits png

On Strokes panel, Depth limit and Ignore back faces are turned off ?

@Carlosan this doesn't work unfortunately, still having same issues and on top of that, preview of your image appears to be black in the stencil menu.
Both Depth Limit and Ignore Back Faces were switched off in this case but I need Ignore Back Faces to be turned on from time to time as I work.

Your stencil have Indexed color mode, this is showing bad results. Changing to RGB color mode or 24bits don't show any difference.

Sincerely I don't know why the Black areas are take as White value.

Black is use to give flat results not modifying the surface, but with this stencil it works inverted.

Sorry, I don't know how to help.
Maybe asking in the Discord chat can give you a better answer.

Yeah it's strange. Even if I adjust image so there are no 100% black pixels at all, it still picks dark areas as 100% white for some reason.

 

Also for some reason when I extrude selection and then undo it, the red selection disappears and image works normal. But sometimes it doesn't happen. Sometimes it happen when I just extrude the image, but when I undo it, the red selection is back. See gif below:
