When I go into the trigger box, the word 'Text' comes up instead of 'Press 'F' to turn light on

Hi everyone

I have been doing the “Introduction to Blueprints” tutorial videos and am now on number 7. In this video, we create two instances of a wall light, and as you enter the trigger box, a message is supposed to display “Press ‘F’ to turn on light”, which I typed in under the ‘text’ section in the ‘details’ panel, however, when I play the game in the preview panel, it still renders ‘Text’!!!

When I moved the player start point trigger back, I noticed also that the player still spawns from the original position, not the updated one. Is there some way of ‘baking’ these changes? What am I doing wrong?

Thanks in advance.
