why i can't choose what condition to display the overlay but have to set it ALWAYS showing

You need to make procedure with logic return type and then select it in this selector

It happens to me too. I created a trigger in the overlay, and when I want to change it to a trigger instead of always, what I created in the overlay doesn't show it there and I don't know what to do.

You can see in the pictures that in the overlay I clicked on the plus in the display overlay in-game, created a trigger and when I returned to the overlay as it always is, the trigger is not there.

Will you write what I should do? Because I need help with that, so that it shows me the trigger on the overlay where always is. Because I struggled with it for more than a day, I tried to delete it and turn it off and restart the PC, but it still doesn't work and it doesn't show.

OK. No more help with that, I figured out why my created trigger didn't show in the overlay under always, because I didn't have everything given in the trigger such as: world, xyz and entity. I only had entities with it, that's why it didn't show.
