Replace the Size and Position of the GridLayout from Offscale to Scale: Make all Offset inside of the both Axis of Size and Position to 0 and insert your Scale number.
I think there is a plugin for that try this: Plugin Try this one first
I might of sent you the wrong one so if that the case it is probably this one:Plugin Try this one last
Hope this helps! I use this for all my gui in my games!
U dont need to use any Plugin for easy things, just go to CellSize and then you will see Offset and Scale, make Offset to 0, and then insert your Number to scale.
Scale does not work like Offset, with Offset you can use 160 but Scale works like that: Scale Full Screen Size is 1. If you want to Scale something to half of a Frame you can do 0.5. Try out 0.25 and the other one 0.3 and just try something out.
why you dont first delete gridlayout and set the slot frame size to 0.1,0,0.1,0 and you set the size what you want then copy the size and re-add the gridlayout and paste the size you copied in cellsize of the gridlayout? that what i do
