I have a couple of dropdown content controls in my .docx-file. Both of them have as "Please select a value"-state font color of red. This is how it also should be.

One of them has font color of black when they are in "Ok, I selected now something as the value"-state. That's how it should be. But one of them has red as the font color, while it should turn to black.

What's the property/setting that I'm missing here and should change to something in order to get the selected value with black font?

edit. Programmatic answer, especially VBA, is easily good enough.
