3 of 4 TextFields reject Text Drop from TextEdit

In a window, I have 4 TextFields and two TextArea.

The first TextField accept Text Drop from TextEdit (Apple), but the other three reject it.

I deleted one TextField and duplicate the one who accept Text Drop, rename it and run: the Text Drop are rejected.

TextAreas accept Text Drop.
