ComboBox List not showing

Hello, I’m trying to use the combobox to create a dropdown list with a couple items in it.

The combobox is in an “effects” class that I made visible.

When I build, a box shows the text “effects” which I added in the class, but I can see the list of items I added in the combobox.

I’m new guys, just looking for some guidance here, thanks. Let me know if you need more information.
