First, welcome to the community and to Construct 2!
Second, for future reference, you can Save As... to a single capx file, which makes it a lot easier to share projects. That way you don't have to zip the files.
Third, regarding the main issue, you have to remember that C2 is event-based, and that the game loop runs through all events in order, from the top of the sheet to the bottom. Thus, your For Each loop is executing every tick of the game loop.
To fix this, create a System -> On Start Of Layout condition, and move your For Each loop block underneath it, as an indented sub-event. Then you should see the results you are looking for.
