I can't select values from a dropdownlist

I have a UI with a canvas and in it I have a panel with a dropdown that loads a list that I can see and that when I pass over it with the ray it reacts to the hover event, but when I select with the trigger sometimes it is selected and sometimes not. …many times I have to hit it many times and it is impossible, however other times it works perfectly.
I can’t find a logical explanation why sometimes it works and other times it doesn’t, I tried quest 2, pro and 3 and in all of them it happens, sometimes it works and other times it doesn’t.
The editor version is 2022.3.30f1, and I am using meta all-in -one 67.0.0.0.
Does anyone know why this is happening to me?
