Identical events work differently

I am trying to create more objects of one type and change the current animation frame for each instance to a random one. The problem is, it works for one object, while it's not working for another object, even though the events are identical.

prntscr.com/e1fuyh this one works well.

prntscr.com/e1fv6t while this one makes the animation frames of all instances of this object the same.

What may cause this?

random(0,1) will only ever pick 0.

But my frames are 0 and 1. How do I pick between those two frames?

int(random(0,2))

But my frames are 0 and 1. How do I pick between those two frames?

choose(0,1)

Okay, the problem was something else, and I've fixed that. Thx
