Unity Social Integration - Facebook Button Not Working?

Hi I have a game that pops up a Facebook button when the game ends so the user can share their highscore (kinda like a flappy bird simple game). The Facebook button works. Alls this does is when the button is clicked take the user to the Facebook app on their iOS device and take them directly to post area of the Facebook app and already have text they can post in their for them which is what it is doing. But in the picture below you will see that it doesn't put the text in the area i want it to (area with red circle) it puts it in that box thing? I want all that text just to be in the area marked by red?

I am not using any plugins either and please don't suggest any as I do not want to use anything beside the Unity Facebook SDK.Thanks in advance (:
