Click (touch) on the Inst Group button in the lower right. Select Customize. At that point you can delete or move instruments, including the instrument in question. (Though, you may need to move the Customize Layout window that pops up out of the way so you can touch on the Vertical Profile instrument.) You can drag instruments around, resize, change color, or delete them. Or click on Add Instrument to see a list of instruments you can add. When done, click on Save and choose whether to change the current instrument layout or create a new one.
