If you just want the text to be displayed on trigger event of every door, then you can do it without using arrays too.

1. Create a public variable for name of your door whose value you will set in level editor (Like you are doing now).

2)Create a string variable in your DoorWidget too.

3. Set a trigger box for this Door BP on whose overlap you will set the value of DoorWidget variable using the widget reference(widget reference created while adding widget to viewport)

4. Add a TEXT component in your widget, and create binding to it. Return the widget variables value in it.

It will print name on widget , everytime player goes into triggerbox of a Door BP
