Quest: Player Dialogue: Subtype and Topic Text boxes are inaccessible

 

I came to the point when I need to fiddle with Player Dialogue section of Quest menu in CK.

And I got stuck without knowing how to deal with the issue I've bumped into:

 

As shown in the picture, the Subtype box and Topic Text box appear to be useless. Subtype box is accessible, but it has nothing in it, it is blank. The Topic Text box is inaccessible at all, inactive, greyed-out.

 

Need some help!
