If you need to change the strip height, you can click the button you see in the following image (the one with the red square around it, tool tipped with View strips in the Application).
You will open a mask where to control the dynamic panel. For example, you can change the height of any strip currently available in the panel, you can delete a strip, or you can even leave it empty (sometimes this is useful when you need to tile just a section of the wall). Have a look at the Panel strips mask and play around with it.
A second (and quicker) way to change strip height is to use the context menu: in Navigation window, click the right mouse button on the strip you want to modify, and select command Strip height->Manual. Pick a graphic reference (in case you have one) for the new height, or type the new value. In the same menu, you find the command that allows you to delete a strip, create an empty (new) one, or even change strip grout.
