Problems ellipse gradient and overprint

[#1]

Dear all,

I've some problems with a ellipse which is colored with an gradient. (1 spot color)

I want to change the ellipse to overprint (attributes / overprint fill).

After this change the aspect ratio will also be changed, I don't know why ?

It seems that the value will be multiply by 2,520775623269. Why?

The ellipse is a delivered file.

If I create a new shape by my own there is no problem with the settings.

Please see example below:

It would be great if anyone could help here.

Thank you and best regards

It's difficult to follow your post and ascertain the problem. The "aspect ratio" of the ellipse did not change; the field that did change is the Scale . . . of the gradient, not the ellipse. I'm not sure why.
