UI Dropdown box

I’m having such a simple issue with the dropdown box, the list that displays underneath the main box is not showing the 3rd option fully.

Does anyone know how I can re-size the list? I’ve tried re-sizing everything humanly possible but nothing seems to be working.

Is the dropdown parented to a mask?

It’s only the child of a Canvas

Can you share the project or a simplified version with just the issue?
