UI resizing not working (auto size)

[Calum_Dev (Calum)]

I just resized my GUI to fit inside a different Frame but as you can see the green button is messed up. It uses Auto Size to fit any text while being the same text size as the others. Any ideas on why this is happening?

Heres the GUI file if this helps:

Seems to only be happening in the scrolling frame
