Problem entering text

Hi! I’m using Rhino 7.7.21160.05002 on macOS 11.4 and I’m having a problem with the text tool.

I select the icon to place a text object and the dialog box is presented. The default text is “Rhino” but no matter what I change the text to, “Rhino” is inserted into the drawing when I click Apply and select a location.

What am I doing wrong please?
