Why is my GUI in a different place when i test it in roblox studios then in the published game?

I was working on a GUI and it give you a confirmation when you click on it to reset and when you click confirm you reset but when i tested it in roblox studios the confirmation box was at a different place then the published game version so it would show up like 10 cms higher on studios then on the published game. How do i fix this?

This is not a gui designing website, please make sure your question is scripting related. But I will still answer your question. This is because the studio does not show where the gui objects will be before the roblox CoreGui is enabled to ignore the (defualt)core gui find the property in your ScreenGui called "IgnoreGuiInSet" and check the box to set it as true.

You have to set the gui's size offset to 0 and only use scale.
