Note that you are leaving, on purpose, point in an invisible part of the
document.

You can reveal text around point with C-c C-r (or even C-u C-c C-r). See
`org-reveal' for details.

By the way, Org 9.0 (yet to be released) contains a variable to control
this: `org-show-context-detail'. You may want to update Org.

I can reproduce the same with Org 7.9.3.
