Why I can't change some properties to the gui while testing?

I can’t change some properties to the gui while testing. This effects the scripts too:

while in studio:

while testing:

Maybe it’s simple to fix or it’s just a setting but I can’t find why. Thanks!

You are changing the values at StarterGui. As soon as you join, the content of StarterGUI is replicated to the client, so you will have to edit the Player’s GUI if you want to see changes take effect.

Changing StarterGui will only affect future clients that will join and receive the updated changes.

FYI: Players > [PlayerName] > PlayerGui

I thought It will be harder XD. I’m just learning new stuff. Thanks a lot for the help!
