UFT .Highlight is working from repository but not from Action

Question

I have some elements in my repo with relative path:

And i have this code in my Action Solution:

Browser("Posventa").Page("Posventa").WebEdit("CampoNroOperacion").Highlight
Browser("Posventa").Page("Posventa").WebElement("DespEventosConPaginado").Highlight
exist = Browser("Posventa").Page("Posventa").WebElement("DespEventosConPaginado").Exist(10)
print("existe en Action: "&exist)

So after execute my Action, 1st Highlight is working ok, but the 2d one doesn't work and exist equals False.

The object DespEventosConPaginado has AVG element, maybe i didn't capture correctly that object. I tried to add aditional values like X and Y or abs_y and abs_X but this did not work.

This is a drop-down that a want to click:

And when i click manual highlight from my repo, its working fine and the object blinks.
