UMG tabbing not selecting TextBox field

I have a UMG with a number of textboxes. When the user enters a value and hits the tab to go to the next field I was hoping it would select the entire text in that textbox like all other OS textboxes. Currently, it sets the cursor at the right end of the textbox field and so if the user enters a new value it will simply add on.

Is there a simple setting I’m missing or do I have to wrap it in a special UI element?
