Hi,
The specifications area will display if you have the frontend display option of your custom field turned on. You should turn it off.
The solution we provide in our FAQ for that problem is what you need to do. If that doesn't work, it means that you're not doing something correctly. For example, if you're editing the view file for another template than your frontend template.
Unfortunately, not knowing how you configured your custom field nor what code you added in which file, I can't say for sure what your problem is.
Could you provide some screenshots so that we can see what you did ?
