How to change submit button

I tried to use the button form designer but it does not seem to be changing. The designer says the button is square but it appears to have rounded corners. I also set the border for the same orange color but there is a white border on it?

This is the button for "See your price >"

I want it to have square corners and all orange with not white border. Thanks!

I have cloned your form and I saw that you selected Rectangle corners, but they appear as Rounded corners.

To fix this issue inside of your Form Designer select Rounded corners and than switch again to Rectangle corners. Also change border width to 2 px and then save your changes.

This should resolve your issue.

After you make this changes your submit button should look like this. 

Here is my cloned form: http://form.jotformpro.com/form/52424811630952? 

Feel free to clone it.
