Left and Right constraint changes the distance to the frame edges when resizing

I set the group constraint to Left and Right but whenever i resize the frame the distance to the edges changes. I thought Left and Right constraint won’t change the distance to the frame edge.

It should work they way you expect it to, unless you have something that prevents the element from shrinking, like a minimum width.

I found it was the Layout Grid Column. I didn’t expected to be that, i thought it was just some kind of layout guide. Thanks
