Thank you @elliot for the quick reply.
Before the update to acf or wp the prepend would display on the front end. E.g. If I had “Title: ” in the prepend and “WordPress 101” in the input field. The front end would display “Title: WordPress 101”.
The displaying of the prepend of the input field is no longer happening. The “Title: ” is not displaying on the front end, just the value put in the field input.
Thanks Elliot.
