How to disable corner visability after gradient?

So i created a gradient for my UI element, and i added rounded box in brush for it, with corners of 20 units. But as you can see on this image

The corners added additional elements/ color to it, Anyone know how to fix it? i will puy my gradient nodes in next post, since new users are stricted to 1 image.

This is my gradient nodes

If you see this form post i resolved it by: go to your material for ui enter it: set the result node(the node that gets all the input from nodes). Material domain to “User Interface” and the set the Blend Mode to “Translucent”just like on the image:
