Unable to edit Text in Textbox Properties box or within the textbox

I have a simple problem. In writer, when I click on Textbox in Form Controls>>create a textbox>>double-click>>properties box comes up, I can’t enter or change the name of the textbox or label names. I am able to enter text in the default area. When I try to test my work (not in design mode), I cannot enter anything in the field. The cursor’s in place, but when I type, nothing happens.
What am I doing wrong?

First Steps

Try Step 1 and 2 and possibly others.
