Hi
I just wondered if this was a bug or intended behaviour? In APEX 20.2 if I have a popup lov with display null value set to yes and no null value label set, there is no way to clear the label (without adding a button, or DA on keypress). Below is a screenshot of inline lov, but it is the same with modal dialog. Adding a null display value also fixes this, but it doesn't look good when you are displaying the item label optional floating template (the null text sits on top of the label text).
In older versions of APEX it is possible to clear the lov by clicking the % sign, e.g 18.1
