You want to spawn a new button after 10 seconds? "Time=10 seconds" is the wrong way to do it. This condition compares the time passed since the game startup, not since the last action.
A simple way to fix it is to add "Wait 10 seconds", but I advise against using Wait with such a long timeout, because in 10 seconds many things can change. It's much safer to use Timer behavior. Or if your countdown sprite is animated, you can use an event "CountdownSprite On animation finished" to spawn a new button and destroy the countdtown sprite.
