I uploaded an video so you can understand better my problem.
Edit: If you prefer, I uploaded the game here: http://www.almeidamarcell.com/indiegames/cesupa-game/index.html
On this video I 'played' the game twice because so you can see what I'm saying. The collision with the edgeMarkers are kind buggy. This time I think I did everything correctly and I'm following the https://www.scirra.com/tutorials/253/how-to-make-a-platform-game/page-6 tutorial.
Here are the screenshot of my animations and my events.
You can also see I created an JumpMarker, because I wanted to make my enemy jump. But if i use two different collisions the first one(edgeMarker) doesn't work.
Anyway, my main problem is on the video. Where the enemy(in black) sometimes colide well with the blue block and sometimes don't. This is an Constructor 2 bug or I'm missing something?
