Grid link Form, Cann't hide "Add New" button in the form

My Form link with the grid as normal, and "Add New " button shown on the grid.

I uncheck the option “Enables the buttons New and Include within the Form”. So I can hide “Add new” button in the form.

It works in the development environment but it doesn’t work in the production environment.

Did I do something wrong? or is this a bug?

Thank you.

Check your toolbar? Form Buttons should be on the Left side

It doesn’t work in the production environment. Thank you for your reminder.

Try going into the PROD environment and deleting the whole folder for that application and upload it fresh

IF above doesn’t work, then clear cookies or try another browser. Sometimes mixing prod and dev in one browser corrupts the cookies.
