Visiting Cards have no closing buttons, own not displayed

• visiting cards do not have a closing button. That means you cannot close the visiting card and return to your previous location, and you have to close the card by opening the "More" drop down menu.
  Please add close button to visiting cards

• when trying to open your own visiting card, the following happens:
  a) from the user search: nothing happens
  b) from the member management in the course: blank screen

should be possible to open your own visiting card, should it not? Or lead to visiting card preview in profile
