Product Options BUG in Abantecart 1.4

[Nuno Neff]

I was inserting a new product on my site and I came across a bug in the product options, I have an option called size, where I have many different sizes and when I add the size option, abantecart adds all the sizes to my product. At first I thought that something was wrong with my site upgrade, but I went to your demo and the same thing happened.
You can try it in your demo, edit a product and then add the Size option and you'll see that this happens.

Hello.
When you add the Global Attribute option for the first time, this behavior is expected. Simply remove any option values you don't need and save your changes.

But in version 1.34 it didn't work like that, in my case I don't like it because imagine I have global attributes with more than 100 options to choose from and then when I add that attribute to the product it adds 100 options and I waste a lot of time just removing the options.
