I've had to add another text field into my Meta Box database and have done so, but when I go to add it to display on an Elementor post template I cannot get it to show at all. Please watch this three-minute video to view what I'm encountering.
I am totally updated with all plugins: Elementor and Elementor Pro v 3.9.2 and Meta Box 5.6.15 and have regenerated permalinks and Elementor CSS, data and library.
You are correct and that fixed my problem. I assumed that, even if the field was empty, the prefix label that was indicated would display. It's obvious now to me that if the field is empty nothing shows.
