Question Changing the state of several animators sequentially in a Coroutine changes them in batches

Ok, what I mean is I have a List of Custom Scripts that each have a function to change the parameter of an animator. I use this for UI effects so I want to run the "Load animation" in a cascade way, that the objects "load" one after the other. So, I decided to make a Coroutine where I call the RunAnimation() function (that essentially is just a call of anim.SetTrigger()) and then do a yield return new WaitForSeconds(0.2f).

The problem is that when I try it, the objects are moved in batches so to say. For example if I have 7 objects in the list, the first 2 will move together, then the next 4 together and then the last one, even though I waited inbetween the calls to change the parameters in the animator.

Here is my code:

Code (CSharp):

1. private void LoadPinsSequence(int chapterIndex)
2.     {
3.         List<PinController> toLoad = new List<PinController>();
4.         switch (chapterIndex)
5.         {
6.             case 0:
7.                 toLoad = chapter1Pins;
8.                 break;
9.             case 1:
10.                 toLoad = chapter2Pins;
11.                 break;
12.             case 2:
13.                 toLoad = chapter3Pins;
14.                 break;
15.         }
16.  
17.         foreach (PinController pin in toLoad)
18.         {
19.             pin.RunLoadAnimation();
20.             yield return new WaitForSeconds(0.2f);
21.         }
22.     }

And the RunLoadAnimation method:

Code (CSharp):

1.  public void RunLoadAnimation()
2.     {
3.         pinAnimator.SetTrigger("Load");
4.     }

Also, the animator state has no exit time, so it should immediately run the animation. Also this only happens with wait times lower than 1 second. I have also tried with WaitForSecondsRealtime(), and also just stalling while measuring the Time.time and elapsed time.

I also tried with the different Animator update modes in the inspector and nothing changes
