Actually now that I think about it, you haven’t specified which actor “overlaps” the trigger volume, so it may be triggering without you realizing and setting your booleans to values you aren’t expecting them to be at by the time the player interacts with the trigger volume. Print a string right after the “on overlap” event and see if they are triggering before the player even reaches them. Your booleans could be reversed from what you expect if they trigger initially when they are instanced during level creation.
