Hi Mark,

Just played around with this a bit...

Apparently, this object has no magnitude data. To get it to
appear, you have to either turn NGC objects 'on', or turn
nebulae 'on' (in the Data Shown dialog). Do that, and it
pops up (as a rectangle, no isophote data), and you can
click on it and ask for 'more info' and so on.
