I dont really work with UI enough to be able to really understand the issue, I tried converting the buttons from size to offset but it doesnt work and I cannot really find any other posts with this problem, the only ones being pretty time consuming and not even sure if they work
Its because while designing UI on roblox studio your screen is smaller basically,
When you test it on roblox launcher your window is bigger! That is what expected.
Offset = Does not change size for window
Size = Does set size for window
